DUPLEXER LESS TRANSCEIVER AND COMMUNICATION APPARATUS

摘要

A duplexer less transceiver arrangement (300) is disclosed. The transceiver comprises a receiver (302) arranged for frequency division duplex communication with a communication network; a transmitter (304) arranged for frequency division duplex communication with the communication network; an antenna port (306) for connecting to an antenna; a balancing impedance circuit (308) arranged to provide an adaptive impedance arranged to mimic the impedance at the antenna port; and an impedance network differentially connecting the receiver (302) transmitter (304) antenna port (306) and balancing impedance circuit (308) wherein the impedance network includes a cross connection.
