Abstract
A digital, radio-frequency (RF) transceiver is modified by coupling an infra-red (IR) communication subsystem thereto. The 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 or RF baseband frequency.
