ABSTRACT:
Switch apparatus including first and second signal switch paths for coupling signal between one of first and second input ports and an output port. Each switch path includes a pair of series-coupled oppositely-poled diodes and a shunt diode having one electrode coupled to the junction of the diode pair, each diode being coupled to the junction by an electrode of like conductivity type. A biasing means selectively biases one of the diode pairs into conduction for coupling signal between one of the input ports and the output port concurrently with the biasing into conduction of the shunt diode coupled to the junction of the other of the diode pairs for biasing the other diode pair into non-conduction, thereby decoupling signal between the other of the input ports and the output port.
