The IC architecture allows the RF designer to provide solutions for three different frequency bands with very few PCB changes, thereby providing faster time to market and reduced development time. The W3020 RF transceiver and W3000 PLL have been designed in conjunction with the SC1 (radio interface and DSP) to provide a complete GSM cellular solution. The W3020 interfaces to the W3000 UHF high-performance PLL IC. The W3020, in combination with the W3000, provides the transmitter, receiver, and frequency synthesizer. Adding a power amplifier(s), filters, and VCO modules completes the radio channel. The baseband modulated signal is applied to the I/Q double-balanced mixer in a differential manner. The 45 phase-shifted local oscillator requires no trim to achieve the required modulation spectral mask. Also, I/Q input signals require no dc offset calibration to achieve high phase accuracy signal. The IF signal outputs from the I/Q mixers are summed and brought out to an external filter that reduces the noise that could be intermodulated into the receive band. This signal is then applied to the low noise up-conversion mixer and brought to the RF output. The received signal is amplified through the low-noise amplifier, which, combined with the preceding filter, dominates the receiver sensitivity. The signal is then 4 Advance Data Sheet December 1999 passed through another external filter to attenuate the image frequency to an acceptable level. The signal passes through the RF down-conversion mixer to the IF frequency. It is then filtered by an external surface acoustic wave (SAW) filter to bring the in-band blocking signals to an acceptable level. The signal is amplified in the IF strip of the receiver. The IF strip contains digital gain control (DGC) amplifiers at both the IF and baseband frequencies and precision lowpass filters. This allows the signal to be amplified while in-band blocking signals are removed. The precision I/Q demodulator splits the signal into its inphase and quadrature signals. The I/Q signals are lowpass filtered and further amplified. The I/Q amplifier contains integrated dc offset calibration circuitry. The outputs (I/Q) are fed to the ADC for further signal processing. The second local oscillator (LO2), comprising a buffer for the external voltage-controlled oscillator (VCO) and a phase-locked loop (PLL), feeds the IF portions of both the modulator and the receiver. An external reference source, voltage-controlled crystal oscillator (VCXO), is divided from 13 MHz to 1 MHz through a counter. The 1 MHz is called the comparison frequency. The VCO frequency of 540 MHz is also divided down to 1 MHz. Both signals are fed into a phase detector, and the resultant error signal is fed through an external low-pass filter to the control input of the VCO. The RF receive and transmit mixers are driven by two band-switchable external VCO modules and buffered internally on the IC. The VCOs are both controlled by a single W3000 PLL synthesizer and loop filter. Fast band-locking is achieved using a proprietary scaling technique integrated in the W3000 PLL.

Lucent Technologies Microelectronics Group employs a human-body model (HBM) and a charged-device model (CDM) for ESD-susceptibility testing and design evaluation. ESD voltage thresholds are dependent on the circuit parameters used to define the model. No industry-wide standard has been adopted for CDM. However, a standard HBM (resistance = 1500 , capacitance = 100 pF) is widely used and, therefore, can be used for comparison purposes. The HBM ESD threshold presented here was obtained by using these circuit parameters: Parameter Method Rating Unit ESD Threshold Voltage HBM 1500 V ESD Threshold Voltage (corner pins) CDM 1000 V ESD Threshold Voltage CDM 500 V Operating Range The device is fully functional within the following operation ranges.

Lucent Technologies Inc. 9 Advance Data Sheet December 1999 W3020 GSM Multiband RF Transceiver LNA The W3020 contains two on-chip LNAs, one to operate in the GSM900 band and one to operate in the GSM1800/1900 bands. The GSM900 operation is combined with the GSM1800 band operation in a dual-band terminal. Only one LNA operates at a time. The two on-chip LNAs with external matching networks are 50 single-ended input, single-ended output type. Switching between the LNAs is determined by the band bit B and the gain control bit G0 in the TR register, as described in the Programming Information section. Table 2.

Advance Data Sheet December 1999 W3020 GSM Multiband RF Transceiver RF Mixer The W3020 contains two mixers: one for GSM900 band operation and one for GSM1800/1900 band operation. The RF mixers are double-balanced mixers that can be used in various modes of operation. The ac-grounded input (pin 56) requires grounding at both the RF and the IF frequencies. If grounding is not placed close to the device, the RF performance will be compromised. At the output, the mixer is connected to a balanced IF SAW filter. Table 4.

The IF amplifier is a balanced-input/balanced-output type and is connected to a balanced SAW filter. It consists of three gain stages: an IF amplifier and two sections of baseband amplifiers. The gain can be changed in steps of 32, 16, 8, and 4 dB. The baseband also contains a level-shifter stage to drive an A/D converter directly. The level-shifter stage has 21 dB of gain that can be switched off. The specifications below are for the two modes of operation. ACTUAL = REQUESTED ACTUAL GAIN ACTUAL GAIN (dB) X 20 dB The gain of the IF section is programmed via the three-wire serial bus. The IF amplifier contains the 32 dB amplifier stage and has a gain of either 0 or 32 dB. The IF amplifier is followed by a quadrature mixer with a fixed gain of 4 dB. The first baseband amplifier (G3, G2, G6) after the low-pass filter and demodulator has gains selectable between 0, 4, 8, 12, 16, 20, 24, and 28 dB. Using the other gain steps, the IF and baseband gain can be varied by 64 dB in 4 dB steps. The second baseband amplifier (G5, G1) has gains selectable between 0, 4, 21, and 25 dB. The 21 dB gain step in the second baseband amplifier section is not tested and should therefore not be used. Figure 3 is a diagram of the gain steps. G4 LPF1 G3 32/0 6 16/0 G2 G6* LPF2 G5* G1 4/0 21/0 4/0 8/0 *Not tested. Figure 3. IF Amplifier Gain Steps The baseband amplifier section contains dc correction circuitry that minimizes dc offsets at the I/Q outputs. The low-pass filters in the baseband contain a selfcalibrating circuit for tuning of filter cut-off frequency. The selectable gain settings are programmed via the TR register as described in the Programming Information section. Filter tuning and dc calibration are also explained in that section. To achieve the specified absolute gain accuracy, the total gain should be calibrated at room temperature. This would normally be part of the overall phone calibration. Absolute gain accuracy measures the gain change over a specified temperature range relative to the room temperature measurement. In the GSM system, this specification is dependent on all the RX functional blocks and not solely on the IF strip. The relative gain accuracy is a measure of the gain stage accuracy over a 20 dB range (see Figure 4). Relative 12 Y REQUESTED GAIN (dB) Note: X , Y = relative gain accuracy. Figure 4. Actual Gain vs. Requested Gain The input impedance of the IF strip will vary slightly when the 32 dB amplifier is switched between the ON and OFF states. We recommend that the IF strip be matched with the 32 dB amplifier in the ON state to provide the best match to the SAW filter when the input level is at a minimum. The input matching network can match the IF input directly to the SAW filter or to 50 . A matching network to 50 was chosen for the evaluation board to allow for convenient laboratory measurements. To keep the input impedance low and minimize impedance variation between gain settings of the IF stage, a resistor is shunt-connected between the input terminals. The input network can then be matched to the desired input impedance. (The specified gain includes a resistor value of 500 .) For testing purposes, the input has been matched to 50 , and the gains of the IF/baseband amplifier are all referred to a 50 matched input impedance. The I/Q outputs are terminated in high-impedance loads. The gains are voltage gains and include the voltage gain in the impedance transformation of the input matching network. The network is illustrated in Figure 5. W3020 G4 bit IFIP PIN 35 R1 500 INPUT IMPEDANCE 50 32/0 1:1 IFIN PIN 34 Note: Balun is shown for testing purposes only. Figure 5.

This voltage gain is measured from the input of the IF strip to either the I or Q channel output. The absolute accuracy refers to the total gain variation from the nominal condition over temperature (-30 C to +85 C) after gain calibration at nominal temperature. The relative gain step accuracy is determined after the 32 dB gain stage has been calibrated at nominal temperature. The total gain step accuracy at any of the possible gain conditions should not vary more than the specified amount within a 20 dB measurement window.

Advance Data Sheet December 1999 W3020 GSM Multiband RF Transceiver Modulator The modulator uses an indirect I/Q modulator architecture that is ideal for multiband operation. The IF modulation improves EVM effects due to improved carrier feedthrough. The series transmit IF filters allow improved wideband noise, which enables duplexer removal. The I/Q modulator requires no amplitude or phase calibration to achieve high phase accuracy.

Some words for time-critical interactions address both W3020 and W3000 at the same time, while some words for initialization address W3020 and W3000 separately. The W3020 gets all of its control information via a three-wire serial bus from the baseband IC. Serial data transfers always consist of 24 bits: 3 bits of address to select one of five control registers, and up to 21 bits of data. The data is shifted first into a shift register and then parallel-loaded into the proper control register after the completion of the transfer when the latch enable signal goes high. The last bit is that which immediately precedes a low-to-high latch input transition occurring while the CLOCK input is low. Bit 24 is loaded first, and bit 1 is loaded last. The four control registers are defined as follows: n TR: Transmit/receive register for W3020. Contains bits for setting various transmit and receive modes, setting receive gain, etc. It is expected that this register would be written several times during a frame. n CONFIG: Contains bits to control various options for dc offset correction, filter-tuning, lock detect, and overload outputs, etc. It is expected that this register would be written once at initialization and then rarely updated. Since it is not affected by the power-on reset circuit, a write to this register should be the first operation performed when accessing the W3020 chip. Also, it is advisable never to update the configuration register while a critical operation is in progress. n MAIN: Main counter and prescaler values for W3000 chip. Used to set mode and band bit functions for the W3020 while programming the W3000. n REF: Reference counter values for W3000. Not relevant to W3020. Table 12.

Lucent Technologies Inc. 21 W3020 GSM Multiband RF Transceiver Programming Information (continued) TR Register (continued) B: Band Select When set low, the GSM900 transceiver circuits are enabled and the GSM1800 transceiver circuits are disabled. When set high, the GSM1800 transceiver circuits are enabled and the GSM900 transceiver circuits are disabled. The transceiver circuits that change with the setting of the band bit B are the LNA, the RF mixer, the receive UHF LO1 buffer, the transmit UHF LO1 buffer, and the LO2 divider for the modulator IF LO phase shifter circuit. The normal LO2 division factor for GSM900 is divide-by-2; for GSM1800, the normal LO2 division factor is divide-by3. Note that bits T2 and T1 also affect the transmitter LO2 division factor when set high (see Table 23 and Table 24). Table 14. B: Band Select B Bit 23 Function 0 GSM900 Path On 1 GSM1800/1900 Path On Note: When programmed via the same three-wire bus as the W3000, updating this bit in W3020 also updates it in W3000, and vice versa. MO[3:1]: Mode Control The various system modes of the W3020 are set by the mode control bits. These are active in both the TR and MAIN registers. The W3000 will also power up with the W3020 in any of the valid modes set by the mode bits in the TR or MAIN registers. The mode bit settings for each W3020 system mode are given in Table 15. The corresponding typical supply current for the IC in each mode is shown in the Supply Currents table on page 9. In sleep mode, both the W3020 and W3000 are powered down, and the supply current is in the A 22 Advance Data Sheet December 1999 range. The transmit PLL settling mode is used prior to a transmit burst in order to power up and lock the LO1 and LO2 VCO/PLL synthesizers and the respective RF and IF LO buffers connecting to the modulator circuit. The LO2 divide-by circuits remain off during this mode. Similarly, the receive PLL settling mode is used prior to the receive dc calibration time slot and subsequent receive burst in order to power up and lock the LO1 and LO2 VCO/PLL synthesizers and the respective RF and IF LO buffers connecting to the RF mixer and IF strip. The RF mixer can be turned on in this mode by setting the C9 (RF mixer on during settling) bit high in the CONFIG register (see Table 30). The transmitter ON mode turns on all the same circuits as the transmit PLL settling mode along with the I/Q modulator and up-conversion mixer. The receiver ON mode turns on all the same circuits as the receive PLL settling mode along, with the LNA (if enabled by the G0 bit--see Table 26), RF mixer, and IF amplifiers and demodulator. When first going into receive mode, a baseband LP filter tune is performed, if requested, by setting the FTR (filter tune request) bit high in the TR register and the C6 (filter tune disable) bit low in the CONFIG register (see Table 20 and Table 35, respectively, and the LowPass Filter Tuning section). Next, a dc offset calibration cycle is performed if the DS (dc correction skip) bit is low in the TR register and the C5 (dc correction disable) bit is low in the CONFIG register (see Table 22 and Table 36, respectively). The default condition is that the LNA turns off during the dc calibration if the C2 (LNA mode during dc calibration) bit is low in the CONFIG register (see Table 37). The other default condition is that the RF mixer LO1 buffer turns off during the dc calibration if the C3 (RX LO1 buffer mode during dc calibration) bit is low in the CONFIG register (see Table 38). During this event, the transmit LO1 buffer will turn on to act as a load stage for the UHF LO1 buffer. (For additional information on the dc offset calibration, see the dc Offset Correction Timing section.) After the dc calibration cycle, all the receive circuits turn on as mentioned above for the receive burst. Lucent Technologies Inc.

The low-pass filter tuning operation is controlled by 3 bits in the control logic: n FTR: filter tune request, in the TR register n C4: low-pass filter bandwidth, in the CONFIG register n C6: filter tune disable, in the CONFIG register If the filter tune disable bit (C6) is programmed high, the filter bandwidth is set to the programmed (nominal) value (see Table 35), and any request for filter tuning from the FTR bit is ignored. The accuracy of the filter bandwidth can be improved by performing a filter tune calibration. A filter tune can be performed by setting the filter tune request (FTR) bit in the TR register high and the filter tune disable bit (C6) in the CONFIG register low. This enables a 13/4 MHz (3.25 MHz) clock to the filter tuning state machine, which then runs until the tuning is complete and the new filter tune values are stored. The filter tune operation itself takes 16.5 cycles of the 3.25 MHz clock, or 5.1 s. The filter tune operation should be done in receive mode. The receive mode needs to be held active for at least 20 s to allow for bias start-up. The dc offset calibration, if requested, is performed after the filter tune is complete. The filter tune operation adds 5.1 s to the total calibration time when requested at the same time as a dc offset calibration. If a filter tune is requested while the MOD bits are not set to 111, only the receive bias circuitry is turned on; the rest of the receive channel remains powered down. Lucent Technologies Inc. 31 W3020 GSM Multiband RF Transceiver Advance Data Sheet December 1999 Programming Information (continued) Filter Tune and dc Offset Correction Timing (continued) dc Offset Calibration The dc offset calibration operation is controlled by several bits in the CONFIG and TR registers: n DS: dc correction skip, in the TR register n DP: dc precharge only, in the TR register n C5: dc correction disable, in the CONFIG register n C7: dc coarse/fine correction, in the CONFIG register n DT: dc correction time, in the CONFIG register When the dc correction disable bit (C5) in the CONFIG register is written high, the dc offset correction circuitry charges to a default value, corresponding to 0 dc offset, and any request for dc offset calibration is ignored. If dc correction disable = 0, the dc offset calibration is initiated by writing the MO bits in the TR (or MAIN) register to a value of 111 while dc correction skip (DS) and dc precharge only (DP) are both low. As in the case of the filter tune, start of dc offset calibration is held off for about 15 s while the bias circuits and input clock buffer start-up. If the FTR bit was also written high coincident with entering RX mode, a filter tune is performed first, after which dc offset calibration begins automatically. The dc offset calibration runs for a time determined by the dc offset correction time bits DT[0:2] in the CONFIG register. There are three of these bits, giving the user a choice of eight different correction times. Upon completion of the dc offset calibration, the 3.25 MHz baseband clock stops and full receive mode is entered automatically, with the LO1 buffer and LNA (if G0 = 1) being enabled automatically. If RX mode is entered with dc precharge only (DP = 1) set high, dc offset circuitry runs through a much shorter calibration routine, after which normal receive mode is entered automatically. The precharge-only operation functions much the same as the normal calibration operation in that the LO1 buffer and LNA is disabled until completion of the precharge operation. The 15 s bias start-up time is still incurred. The receive circuitry conditions during dc calibration are also controlled by two other bits in the CONFIG register: n C2: LNA on during dc calibration, when high n C3: receive LO1 buffer on during dc, calibration when high For both the standard dc offset calibration cycle and the dc precharge-only operation, it is possible to perform dc offset calibration with the LNA and/or LO1 buffer on by setting the C2 and C3 bits in the CONFIG register. 32 Lucent Technologies Inc. Advance Data Sheet December 1999 W3020 GSM Multiband RF Transceiver Programming Example This programming example shows how the W3020 can be programmed after power-on and how it can be programmed prior to receive and transmit bursts. The reference register for the W3000 is initialized separately with the reference divider ratio, as described in the W3000 data sheet. Table 43. Initialize CONFIG Register (Reset W3020) To reset all registers to their default state and put the device into a low-power sleep mode, one write to the CONFIG register is necessary. This will also reset W3000 if it is connected on the same three-wire bus. Normally, the device will be both reset and configured in the same programming as follows: CONFIG register: reset device, set dc calibration time to max value (486 s), set phase detector polarity for the positive slope VCO, use high BW and coarse dc offset tune.
