Abstract
For example, in a conventional high frequency switch used for a mobile phone and so on, high frequency distortion is caused by a diode which is turned off upon transmission. A high frequency switch includes a switch circuit for switching transmission and reception performed via a transmitting terminal and receiving terminals, said switch circuit having a diode turned off upon transmission, and a low-pass filter for suppressing high frequency distortion caused by the diode upon transmission.
