RF transceiver with distributed filtering topology

A radio frequency (RF) transceiver having a distributed duplex filtering topology comprising:

• a tunable RF duplexer configured to input an RF receive input signal that operates within an RF receive band of an RF communication band from an antenna, generate an RF receive output signal that operates within the RF receive band in response to the RF receive input signal from the antenna, and simultaneously output an RF transmission output signal that operates within an RF transmission band of the RF communication band to the antenna and input the RF receive input signal from the antenna;
• a low noise amplifier (LNA) comprising a linear amplification stage and a tunable high-selectivity bandpass filter, wherein:
• the linear amplification stage is coupled to receive the RF receive output signal from the tunable RF duplexer, and is configured to amplify the RF receive output signal;
• and
• the tunable high-selectivity bandpass filter is tunable to provide a passband within the RF receive band, and is coupled to receive the RF receive output signal after amplification by the linear amplification stage.
