Full-duplex transceiver with distributed duplexing function

A dual wireless transceiver and a circuit and a connecting, comprising a link receiving, transmission and link duplexer. Transmitting the link comprising a filter part, solution for the access frequency range from the transmitting the signal attenuation by stop-band attenuation; the attenuation equal to or greater than the frequency range access an duplexer stop-band attenuation. Similar, and a concave part and they, so the transmission frequency band by stop-band attenuation the signal attenuation; the attenuation equal to or greater than the transmission frequency band an duplexer stop-band attenuation. The biasing control circuit is radio signals and power layer and link transmission time, detecting and responded the power layer of amplifier to the link receiving.
