Patent ID: 7633357

Claim:
An SPST (single-pole single-throw) switch for controlling propagation of a high frequency signal between an input terminal and an output terminal, said SPST switch comprising: a plurality of field-effect transistor (FET) switches, each of said plurality of FET switches is connected in parallel with each other, and each of said plurality of FET switches having a field-effect transistor whose drain and source are directly connected in parallel with an inductor, wherein the input of said plurality of FET switches is directly connected to the input terminal of said SPST switch and the output of said plurality of FET switches is directly connected to the output terminal of said SPST switch; each of said field-effect transistors has an ON state and an OFF state changed by a voltage applied to a gate of each of said field-effect transistors, and each of said field-effect transistors has an OFF capacitance that causes parallel resonance with said inductor connected at a frequency of the high frequency signal.
