For FM/FSK reception the IF tank used in the phase coincidence demodulator can be constituted either by a ceramic resonator or an LC tank (optionally with a varactor diode to create an AFC circuit). In ASK configuration, the RSSI signal is feed to an ASK detector, which is constituted by the operational amplifier. Demodulation Type of receiver FM / FSK narrow-band RX with ceramic demodulation tank FM / FSK wide-band RX with LC demodulation tank ASK RX with RSSI-based demodulation The superheterodyne configuration is double conversion where MIX1 and MIX2 are driven by the internal local oscillator signals LO1 and LO2, respectively. This allows a high degree of image rejection, achieved in conjunction with an RF front-end filter. Efficient RF front-end filtering is realized by using a SAW, ceramic or helix filter in front of the LNA and by adding an LC filter at the LNA output. A single-conversion variant, called TH71101, is also available. Both Receiver ICs have the same die. At the TH71101 the second mixer MIX2 operates as an amplifier. The TH71102 receiver IC consists of the following building blocks: " " " " " " " " " 1.2 ! ! ! ! ! ! ! ! ! ! PLL synthesizer (PLL SYNTH) for generation of the first and second local oscillator signals LO1 and LO2 Parts of the PLL SYNTH are the high-frequency VCO1, the feedback dividers DIV_8 and DIV_2, a phase-frequency detector (PFD) with charge pump (CP) and a crystal-based reference oscillator (RO) Low-noise amplifier (LNA) for high-sensitivity RF signal reception First mixer (MIX1) for down-conversion of the RF signal to the first IF (IF1) Second mixer (MIX2) for down-conversion of the IF1 to the second IF (IF2) IF amplifier (IFA) to amplify and limit the IF2 signal and for RSSI generation Phase coincidence demodulator (DEMOD) with third mixer (MIX3) to demodulate the IF signal Operational amplifier (OA) for data slicing, filtering and ASK detection Bias circuitry for bandgap biasing and circuit shutdown Technical Data Overview Input frequency range: 300 MHz to 450 MHz Power supply range: 2.3 V to 5.5 V @ ASK Temperature range: -40 C to +85 C Standby current: 50 nA Operating current: 6.5 mA at low gain mode 8.2 mA at high gain mode 1) Sensitivity: -111 dBm with 40 kHz IF filter BW 2) Sensitivity: -104 dBm with 150 kHz IF filter BW Range of first IF1: 10 MHz to 80 MHz Range of second IF2: 400 kHz to 22 MHz Maximum data rate: 80 kbit/s NRZ !

The receiver's double-conversion architecture requires careful frequency planning. Besides the desired RF input signal, there are a number of spurious signals that may cause an undesired response at the output. Among them are the image of the RF signal (that must be suppressed by the RF front-end filter), spurious signals injected to the first IF (IF1) and their images which could be mixed down to the same second IF (IF2) as the desired RF signal (they must be suppressed by the LC filter at IF1 and/or by low-crosstalk design). By configuring the TH71102 for double conversion and using its internal PLL synthesizer with fixed feedback divider ratios of N1 = 8 (DIV_8) and N2 = 2 (DIV_2), four types of down-conversion are possible: low-side injection of LO1 and LO2 (low-low), LO1 low-side and LO2 high-side (low-high), LO1 high-side and LO2 low-side (high-low) or LO1 and LO2 high-side (high-high). The following table summarizes some equations that are useful to calculate the crystal reference frequency (REF), the first IF (IF1) and the VCO1 or first LO frequency (LO1), respectively, for a given RF and second IF (IF2).

As for example: the first IF and the image frequencies should not be in a radio band where strong interfering signals might occur (because they could represent parasitic receiving signals), the LO1 signal should be in the range of 300 MHz to 450 MHz (because this is the optimum frequency range of the VCO1). Furthermore the first IF should be as high as possible to achieve highest RF image rejection. The columns in bold depict the selected frequency plans to receive at 315 MHz and 433.92 MHz, respectively. 390107110201 Rev. 005 Page 5 of 14 EVB Description Feb./03 L1 VCC ENRX C4 IN_LNA GND RO SAWFIL VCC VCC C5 L2 C2 R1 CB2 C3 C1 C_RO XTAL 25 VEE CB8 CB1 32 VCC 31 IN_LNA 30 VEE 29 LF 28 ENRX 27 VCC 26 RO 1 OUTP 23 2 GAIN_LNA C14 C15 C16 1 2 4 C7 C6 3 L3 L4 5 6 L5 C8 7 16 VEE 10 IN_IFA 11 FBC1 12 FBC2 13 VCC 14 OUT_IFA 15 CB5 CB6 CB7 8 C13 VCC CB3 OUT_MIX2 9 1 2 TH71102 VEE 22 OUT_LNA 1 2 1 2 RSSI 21 IN_MIX1 1 2 OUTN GND 24 1 2 OAN 19 OUTP GND VEE OAP 20 VEE Page 6 of 14 IF1P VCC 17 RSSI GND OUT_OA GND OUT_OA 18 390107110201 Rev. 005 IF1N Fig. 2: VCC R2 C9 C12 CB4 CP GND VCC CERFIL C10 C11 VCC CERRES R_Q L_OPT C_OPT 2 1 2 FSK output EVB71102 315/433MHz Receiver Evaluation Board Description FSK Application Circuits Circuit diagram for FSK reception EVB Description Feb./03 EVB71102 315/433MHz Receiver Evaluation Board Description 2.1 PCB Top View for FSK Reception VCC Evaluation Board CB6 C_OPT CERFIL R2 CP C9 C8 L3 32 1 24 25 C7 0 C6 0 CB1 L2 OUTP C3 C2 C14 OUTN 5 6 7 L1 IN_LNA ENRX C4 Board size is 44mm x 54mm Page 7 of 14 RF_input VCC RO 1 R1 C_RO XTAL 2 SAWFIL TH711xx_ev03_EB_11/00_B CB2 C5 3 C1 390107110201 Rev. 005 L5 L4 0 C15 CB5 9 8 17 16 TH71102 RSSI C16 0 CB7 CB4 OUT_OA CB3 C12 R_Q CB8 CERRES C10 C11 L_OPT C13 TH7111xx Melexis Board layout data in Gerber format is available EVB Description Feb./03 EVB71102 315/433MHz Receiver Evaluation Board Description 2.2 Board Component Values for FSK (Fig. 2) Value Value @ 315 MHz @ 433.92 MHz 15 pF 15 pF 10% crystal series capacitor NIP NIP 10% optional loop filter capacitor 1 nF 1 nF 10% loop filter capacitor NIP 3.3 pF 5% capacitor to match to SAW filter input 0603 NIP 3.3 pF 5% capacitor to match to SAW filter output 0603 5.6 pF 4.7 pF 5% LNA output tank capacitor C7 0603 4.7 pF 2.2 pF 5% MIX1 input matching capacitor C8 0603 27 pF 27 pF 5% IF1 tank capacitor C9 0805 33 nF 33 nF 10% IFA feedback capacitor C10 0603 1 nF 1 nF 10% IFA feedback capacitor C11 0603 1 nF 1 nF 10% IFA feedback capacitor C12 0603 1.5 pF 1.5 pF 5% DEMOD phase-shift capacitor C13 0603 680 pF 680 pF 10% DEMOD coupling capacitor CP 0805 10 -
