Wireless computer mouse operation may be provided by receiving a user detection signal from a sensor of the wireless computer mouse to determine the presence of a user. In one embodiment, an operation mode of the wireless computer mouse may be determined by a controller based, at least in part, on the user detection signal. Thereafter, the controller can enable at least one of a short range wireless communication module and a FM transceiver of the wireless computer mouse based on the operation mode determined by the controller.

An impedance matching circuit for a radio receives antenna signals and has its matching elements, such as capacitors, progressively switched into the circuit, with the matching element configuration resulting in the highest RSSI being subsequently used until a succeeding test or antenna impedance change. The effect of the matching circuit is accounted for in the transmitter calibration routine so that the matching circuit works for both half duplex and full duplex.
