ABSTRACT:
A high-frequency switch in which required resistors can be mounted without hampering the characteristics of the switch. The high-frequency switch has a series circuit formed of a first diode and a first transmission line with a node E therebetween. The first diode is connected to a transmitting circuit through a capacitor at a node A. One end of the first transmission line is coupled to a receiving circuit via a capacitor at a node B. A second transmission line and a capacitor with a node C therebetween are connected between the node A and a ground potential, while a second diode and a capacitor with a node D therebetween are coupled between the node B and a ground potential. A series circuit formed of first and second resistors with a node F therebetween is connected between the nodes C and D. A first control voltage terminal Vc1 is coupled to the node C via a resistor, while a second control voltage terminal Vc2 is connected to the node D via another resistor. An antenna ANT and the node E are connected to the node F.
