High frequency switch circuit
First Claim
1. A high-frequency switch circuit comprising:
- a plurality of high-frequency switch means for passing and blocking a high-frequency signal between an input terminal and an output terminal depending on a control potential applied as a control signal;
detecting means for detecting the high-frequency signal which passes through said high-frequency switch means; and
a control potential generating circuit for changing the control potential applied to at least one of said plurality of high-frequency switch means in order to increase difference between the control potential applied to the high-frequency switch means which is in an ON-state and the control potential applied to the high-frequency switch means which is in an OFF-state, depending on an amplitude of the high-frequency signal detected by said detecting means.

Abstract
A high-frequency switch circuit has a plurality of high-frequency switches for passing and blocking a high-frequency signal between an input terminal and an output terminal depending on a control potential applied as a control signal, a high-frequency detecting terminal for detecting high-frequency signal passing through the high-frequency switch which is in ON-state, and a voltage boosting circuit for generating a potential for increasing the control potential applied to the high-frequency switch which is in ON-state in order to increase difference between the control potential applied to the high-frequency switch which is in an ON-state and the control potential applied to the high-frequency switch which is in an OFF-state, depending on an intensity or amplitude of the detected high-frequency signal.
