Abstract:
1. A high frequency semiconductor switch having a plurality of field effect transistors able to implement wireless communications by switching an application of voltage to a gate of each field effect transistor, the high frequency semiconductor switch characterized in that, the plurality of field effect transistors each include a source region and a drain region formed on a substrate to be spaced apart by a predetermined distance, a gate formed on the substrate so as to be disposed at the predetermined distance, a source contact formed on the substrate so as to be connected with the source region, and a drain contact formed on the substrate so as to be connected with the drain region, and among the plurality of field effect transistors, a distance between a source contact and a drain contact of a reception terminal side transistor connected with a reception terminal side is longer than a distance between a source contact and a drain contact of a transmission terminal side transistor connected with a transmission terminal side.
