Patent ID: 8493128

Claim:
A switch apparatus for communicating a signal received on a first port to a second port as a function of a first control signal, CS 1 , including: a first switch module, SW 1 coupled to the first port and an intermediate port, the SW 1 including at least one controllable element, CE 1 , the CE 1 controlled by the CS 1 and having an off capacitance, OC 1 ; a second switch module, SW 2 coupled to the intermediate port and the second port, the SW 2 including at least one controllable element, CE 2 , the CE 2 controllable by the CS 1 and the CE 2 having an off capacitance, OC 2 ; and a first shunt module, SH 1 coupled to the intermediate port and ground, the SH 1 including at least third controllable element, CE 3 , the SH 1 controllable by a second control signal, CS 2 , wherein OC 1 is greater than OC 2 .
