ABSTRACT:
A high-frequency switch in which insertion losses can be reduced and a wiring pattern for supplying control voltages can be simplified. The high-frequency switch has first through fourth ports. A transmission line is connected between each pair of the ports, thereby connecting the pairs of ports to each other. A respective capacitor is coupled between each of the ports and a corresponding one of the nodes between the respective transmission lines. A diode is connected between each of said nodes and a reference potential. A capacitor is coupled between the reference potential and each of the diodes. First through fourth control voltage terminals are connected to respective nodes between each of the diodes and the corresponding capacitors.
