Abstract:
A high frequency switch device includes a branch transmission line corresponding to each output terminal provided with a switching part. In the branch transmission line, the switching part includes a transmission side diode provided in such a manner that a cathode thereof is arranged on a side of an input terminal 41 and an anode thereof is arranged on a side of the output terminal, and a ground side diode provided in such a manner that a cathode thereof is grounded and an anode thereof is electrically connected between the output terminal and the transmission side diode in the branch transmission line. The branch transmission line includes a first capacitor and a second capacitor on the side of the output terminal from the transmission side diode in such a manner that the anode of the ground side diode is connected between the first capacitor and the second capacitor.
