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.
