SWITCH CIRCUIT AND SEMICONDUCTOR DEVICE

摘要

Provided is a switch circuit for passing or interrupting high frequency signals. The switch circuit has a correction circuit for correcting an impedance component, which exists in the switch circuit and asymmetrically varies with a direct current potential as a reference, so that the impedance viewed from one of high frequency terminals symmetrically changes with the direct current potential as a reference, to positive/negative changes of the high frequency signal with the direct current potential as a reference.
