Abstract
A duplexer-less transceiver arrangement is disclosed. The transceiver comprises a receiver configured for frequency-division duplex communication with a communication network; a transmitter configured for frequency-division duplex communication with the communication network; an antenna port for connecting to an antenna; a balancing impedance circuit arranged to provide an adaptive impedance arranged to mimic the impedance at the antenna port; and an impedance network differentially connecting the receiver, transmitter, antenna port and balancing impedance circuit, wherein the impedance network includes a cross-connection.
