Dual communication/single antenna duplexer designed to provide operation between two transceivers and one antenna. In the de-energize mode, the diplexer acts as a 3 dB coupler with the output ports isolated by 20dB. Control voltage actuated by the microphone circuit switches the antenna to transmitter No. 1 or transmitter No. 2.
