A transceiver includes a first mixer and a detector in the receive signal path and a second mixer and modulator in the transmit signal path, all of which are coupled to and are operated by programmable counter circuits clocked by a single reference frequency generator. In one embodiment, a charge transfer device filter, which is connectable to both the receive and transmit signal paths by a switch and which has an adjustable bandwidth and center frequency, is also coupled to and operated by a programmable counter circuit which is clocked by the single reference frequency generator.
