Semiconductor switch

摘要

The present invention, which aims at providing a semiconductor switch capable of reducing harmonic distortion, is made up of: an input terminal 101 ; an output terminal 102 ; a through FET 106 that is connected serially to the signal path between the input terminal 101 and the output terminal 102 ; a shunt FET 107 that is connected in between the output terminal 102 and the ground; and a distortion reducing circuit 120 that is connected in parallel with the through FET 106 . In this semiconductor switch, the distortion reducing circuit 120 includes: a first diode 109 and a second diode 110 that are placed in parallel with each other; a first constant voltage source 111 and a second constant voltage source 112 that are placed in parallel with each other; and a FET 108.
