ABSTRACT:
In accordance with the present invention there is provided a common antenna signal path selectively coupled to a plurality of signal energy paths, including transmitter and receiver paths. The transmitter and receiver paths are selectively coupled to the common antenna signal path by semiconductive devices capable of being variably biased from conductive to nonconductive states. In the transmit mode, the magnitude of the RF signal energy is detected and developed to adaptively maintain the disabled semiconductive device in a reverse biased or nonconducting state.
