ABSTRACT:
A low loss high frequency transmitting/receiving switching module (100) having an input and output port (106,110), that individually may be connected to an antenna or external port (108,112) by applying an appropriate bias potential to a switching circuit (140). The switching circuit (140) is designed to operate with only a single diode (130). This is accomplished by using two, four-port 3 db directional couplers (102,104) connected with two coupling lines (114,118). The switching diode (130) is used to add or delete a transmission line (142) in one of the coupling lines (118) to proved a signal phase shift. The switching circuit (140) switches in or out a 180 degree phase shift to change the phase relationship between signals in the two sets of coupling lines (114,116,118,120) to determine which ports (106,108,110,112) of the directional couplers (102,104) are interconnected.
