TH71101

 PLL synthesizer (PLL SYNTH) for generation of the local oscillator signal LO
 Parts of the PLL SYNTH are the high-frequency VCO1, the feedback divider DIV_16,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 IF
 IF pre amplifier which is a mixer cell (MIX2) that operates as an amplifier IF amplifier (IFA) to amplify and limit the IF 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
