12V TIMING/MODULATION FROM MCU 3V 2-INPUT MUX BAND PASS FILTER RESONANCE ANTENNA AMP MUTE Figure 1 Transmitter block diagram 8. RX amplifier Receiver coil is tuned to max receiver sensitivity. Low noise amplifier amplify received signal for MCU ADC conversion. MCU receive differential signal for BPSK detection. There is no RX only function mode on this device, TX is always functional and so receiver only mode cannot be measured.
