Patent ID: 7019602

Claim:
A high isolation RF switch comprising: a transition switch having an output coupled to a slabline transmission line, a first input, a second input and means for coupling either the first or second input to the output; a first input switch having an output coupled to the first input of the transition switch, a first RF input and means for coupling a first RF input port to the first RF input and for decoupling the first RF input port from the first RF input; a second input switch having an output coupled to the second input of the transition switch, a second RF input and means for coupling a second RF input port to the second RF input and for decoupling the second RF input port from the second RF input; a grounded conductor situated between the first and second RF input ports to provide isolation; and means for controlling the transition, first input and second input switches such that one of the first and second RF input ports is coupled to the slabline transmission line and the other of the first and second RF input ports is decoupled from the slabline transmission line.
