ABSTRACT:
A transmit-receive switching circuit is provided for switching a transmitter and a receiver to common antenna via a common signal path. A circulator is employed in the common signal path. The flow of transmitter RF energy and received RF energy is controlled through the circulator by a selectively actuable impedance element coupled to the circulator.
