ABSTRACT:
A high frequency switch includes a main line electrode arranged on a substrate so as to extend between two terminals, a short stub line electrode on the substrate of which one end is connected to a one-side edge of the main line electrode, and the other end is grounded, an open stub line electrode on the substrate of which one end is connected to the other-side edge of the main line which is opposed to the one-side edge, and the other terminal is opened, ground electrodes arranged on the substrate adjacent to the short stub line electrode and the open stub line electrode in the width direction thereof, a semiconductor activation layer disposed in a portion of the substrate between the side edge at least on the one-end side of the open stub line electrode and the ground electrode so as to extend under the open stub line electrode and under the ground electrode, and a gate electrode disposed on the semiconductor activation layer between the open stub line electrode and the ground electrode so as to extend along the longitudinal direction of the open stub line electrode, whereby an FET structure is provided.
