摘要： A compact high frequency switch needing no external control signal is obtained. The high frequency switch includes an anti-parallel diode (first anti-parallel diode) having one end and another end coupled with an antenna terminal (first high-frequency-signal input/output terminal) and a transmitting terminal (second high-frequency-signal input/output terminal), respectively, and becoming a conduction state in the input power not less than predetermined high frequency power. When the high frequency switch is an SPDT type, such a switch may include a ¼-wavelength line in the use frequency of the high frequency switch having one end and another end coupled with the antenna terminal and a receiving terminal (third high-frequency-signal input/output terminal), respectively, and an anti-parallel diode (second anti-parallel diode) coupled between the receiving terminal and a ground and becoming a conduction state in the input power not less than predetermined high frequency power.
