Patent ID: 7893790

Claim:
An electronic device comprising: an impedance matching network including a first and a second micro-electromechanical switch assembly on a substrate; a first line connected between the first switch assembly and the second switch assembly, the first line having a first impedance; a second line connected between the first switch assembly and the second switch assembly, the second line having a second impedance, the first switch assembly having an input terminal and a first and a second output terminal connected to the first and the second line respectively, and the second switch assembly having an output terminal and a first and second input terminal connected to the first and second line respectively; and a tunable micro-electromechanical capacitor connected to at least one of the first line and the second line, wherein the first switch assembly is configured to, in one switching condition thereof, connect the input terminal of the first switch assembly to the first input terminal of the second switch assembly via the first output terminal and the first line, and to, in another switching condition thereof, connect the input terminal of the first switch assembly to the second input terminal of the second switch assembly via the second output terminal and the second line.
