Description
The W3020 is a highly integrated GSM transceiver
designed to operate in dual-band handsets or in
single-band handsets operating at 900, 1800, and
1900 MHz frequency bands (1900 MHz performance
is not verified in production). 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
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 low-
pass 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 in-
phase and quadrature signals. The I/Q signals are low-
pass 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.

ESD Precautions
Although protection circuitry has been designed into this device, proper precautions should be taken to avoid
exposure to electrostatic discharge (ESD) during handling and mounting. 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 Ω,
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:

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 Ω
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.

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.

IF/Baseband Amplifier
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 base-
band 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.
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.

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 self-
calibrating 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
gain accuracy is determined after calibration of the
32 dB amplifier.
Note:=Y,X 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 Ω.
A matching network to 50 Ω 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 Ω.) For
testing purposes, the input has been matched to 50 Ω,
and the gains of the IF/baseband amplifier are all
referred to a 50 Ω 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.

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. The modulator can be altered between GSM900 transmit mode (TX
IF = 270 MHz) and GSM1800/1900 transmit mode (TX IF = 180 MHz) by the band bit setting in the TR register.

The Data Word
The W3020 and W3000 chips are addressed through the bit content of the 24-bit serial word. 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.

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-by-
3. Note that bits T2 and T1 also affect the transmitter
LO2 division factor when set high (see Table 23 and
Table 24).

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 µA
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 Low-
Pass 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.

The CONFIG register 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.

Filter Tune and dc Offset Correction Timing
Low-Pass Filter Tuning
The W3020 has an internal calibration to improve the accuracy of the low-pass filter bandwidth. The filter tune
operation should be performed each time supply voltage is applied to the device and after restart.
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 µs.
The filter tune operation should be done in receive mode. The receive mode needs to be held active for at least
20 µs 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 µs 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.

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 µs 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 µs 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.

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 µs), set phase detector polarity for the
positive slope VCO, use high BW and coarse dc offset tune.
