IR/RF radio transceiver and method

DETAILED DESCRIPTION The invention resides in coupling an infra-red (IR) communication subsystem to a radio-frequency (RF) transceiver.
The IR subsystem includes an IR transmitter and receiver which may be coupled selectably by a switch to a data signal channel or source in the transceiver.
Preferably, the IR receiver includes,an inductor and a diode coupled in parallel, such that the IR receiver detects an IR signal, in significant part, by resonating such signal substantially at a detection frequency.
