Thanks for your great answer Matt. I have another quick question. We know that the controllable range of rx-gain is 0 to 90dB in RFX-2400 d'board. But I only can find a programable gain amplifier in ADC chip whose range is 0 to 20dB. Where is the received signal actually amplified according to the 'rx_gain' value?
Yes. There is a 70dB analog programmable gain amplifier in the Quadrature Demodulator chip, the AD8347.
