RF SWITCH WITH HIGH ISOLATION PERFORMANCE

摘要

Provided is a RF switch for switching a path of a RF signal using a semiconductor transistor such as a field effect transistor (FET). The RF switch includes a plurality of resonators connected to a RF transmission line, and at least one of switching elements connected in shunt or in series between the plural of resonators. The plurality of resonators resonate by interacting with the switching elements when the switching elements are shorted or open.
