Abstract
A switch circuit for passing or blocking a high-frequency signal includes a correction circuit for correcting an impedance component that exists in the switch circuit and that changes asymmetrically with the direct-current potential as a reference such that impedance as seen from either high-frequency terminal changes symmetrically with the direct-current potential as a reference in response to positive and negative changes that take the direct-current potential of the high-frequency signal as a reference.
