ABSTRACT:
A diode network includes a series branch coupled between two signal ports and a shunt branch coupled between a node in the series branch and ground and connected in parallel with a transistor of a latching circuit that is further coupled to supply forward bias to the shunt branch and reverse bias to the series branch when the transistor is conductive for blocking RF signal flow between the ports. The bias applied to the branches is reversed when the latch transistor is non-conductive thereby enabling RF signal flow between the ports. The transistor provides plural functions of establishing positive feedback for the latch, supplying forward and reverse bias to the shunt and series branches, respectively, and enhancing the attenuation of the shunt branch when conductive.
