PROBLEM TO BE SOLVED: To provide a high frequency switch that has a reduced circuit scale while properly maintaining harmonic characteristics in a transmission path of a high frequency signal. SOLUTION: A high frequency switch includes: a transmission port 10; a reception port 20; a common port 30; a transmission side series switch 40; a transmission side shunt switch 50; a reception side series switch 60; and a reception side shunt switch 70. The transmission port inputs a transmission signal, the reception port outputs a reception signal, and the common port either transmits the transmission signal or receives the reception signal. The transmission side series switch is connected between the transmission port and the common port, the transmission side shunt switch is connected between the transmission port and a ground, the reception side series switch is connected between the reception port and the common port, and each switch is a body contact type FET. The reception side shunt switch is connected between the reception port and the ground, and is a floating body type FET. COPYRIGHT: (C)2012,JPO&INPIT |
