Abstract

Provided is a switch having a structure having an excellent isolation characteristic even without a limiter in an ultrahigh frequency hand used for a military component. A switch according to an embodiment of the present invention comprises: multiple transistors which are connected in parallel to a path from an input terminal toward an output terminal and perform switching; and a first transmission line provided between the input terminal and a node on a path to which a first transistor is connected. By the present invention, switching can be performed in an ultrahigh frequency such as W-band while a GaN transistor is used, an insertion loss is low, an isolation characteristic is excellent, and eventually efficiency of an ultrahigh frequency circuit can be further enhanced.
