Patent ID: 6903623

Claim:
A high isolation switch comprising: a balanced line including: a first conductor having an input section and an output section, and a second conductor having an input section and an output section; a first switch connected in series between the input and output sections of the first conductor; a second switch connected in series between the input and output section of the second conductor; a third switch cross connected between the input section of the first conductor and the output section of the second conductor; and a fourth switch cross-connected between the input section of the second conductor and the output section of the first section, wherein an anode of the first switch and an anode of the third switch are connected at the input section of the first conductor, wherein an anode of the second switch and an anode of the forth switch are connected at the input section of the second conductor, wherein a cathode of the first switch and a cathode of the fourth switch are connected at the output section of the first conductor, and wherein a cathode of the second switch and a cathode of the third switch are connected at the output section of the second conductor.
