A differential transceiver circuit coupled to a single antenna interface, the transceiver circuit comprising: a differential pair of signal paths, comprising a first signal path and a second signal path; differential amplifier, having an input arranged to receive a receive signal from the antenna interface; a differential transmitter arranged to generate a differential pair comprising a first transmit signal connected to the first signal path and a second transmit signal connected to the second signal path; a switching network arranged to divert the amplifier output on the second signal path to a signal ground node. The receive signal on one signal path is diverted to ground. The transmit signal corresponding to the other differential signal path is inserted so that the same transmit signal is present on both differential signal paths. When processed by differential downstream components with high common-mode rejection, the transmit signals cancel out.
A differential transceiver circuit for transmitting and receiving via a single antenna interface, the transceiver circuit comprising:
A method of duplex operation of a differential transceiver circuit via a single antenna interface, wherein the transceiver circuit comprises:
