Abstract

See full text

A transceiver arrangement comprises a receiver arranged for frequency-division duplex communication with a communication network; a transmitter arranged for frequency-division duplex communication with the communication network; an transmission port for connecting to an antenna; a balancing impedance circuit arranged to provide an adaptive impedance arranged to mimic the impedance at the transmission port; and a filtering arrangement, which comprises filters of a first type and filters of a second type, connecting the receiver, transmitter, transmission port and balancing impedance circuit. The filters of the first type are arranged to pass signals at transmitter frequency and attenuate signals at receiver frequency and are connected between the transmitter and the transmission port and between the receiver and the balancing impedance circuit. The filters of the second type are arranged to attenuate signals at transmitter frequency and pass signals at receiver frequency and are connected between the transmitter and the balancing impedance circuit and between the receiver and the transmission port. A communication device, a method of operating the transceiver, and a computer program are also disclosed.
