According to the invention, a radio (10) having full-duplex and half-duplex capability, provides for a power amplifier (12) having an output port, a receiver (20) having an input port (19), and a duplexer (44) having an antenna port (40), a transmitter port (36), and a receiver port (38). The present invention further comprises a switching means (22) coupled to the power amplifier (12) output port and the receiver input port (19) for selectively either simultaneously coupling the power amplifier (12) output port to the duplexer transmitter port (36) and the receiver input port (19) to the duplexer receiver port (38) for duplex operation, or alternately coupling the amplifier (12) output port to the duplexer receiver port (38) for half-duplex operation. |
