Provided is a high frequency switch wherein first switch circuits, each of which includes a first PIN diode, are connected in parallel to one or more firstλ/4 signal transmitting paths which transmit transmitting signals, and second switch circuits, each of which includes a second PIN diode, are connected in parallel to one or more secondλ/4 signal transmitting paths which transmit receiving signals to a receiving terminal. A first control voltage is applied to the cathode of the first PIN diode, and a second control voltage is applied to the cathode of the second PIN diode. Furthermore, a biasing circuit which applies a constant bias voltage is connected to each anode of the first PIN diode and the second PIN diode.
