摘要
A high-frequency switch has a first transmission-reception switching circuit for selectively switching between the signal transfer between an antenna terminal and a first transmitting-circuit terminal and the signal transfer between the antenna terminal and a first receiving-circuit terminal; a second transmission-reception switching circuit for selectively switching between the signal transfer between the antenna terminal and a second transmitting-circuit terminal and the signal transfer between the antenna terminal and a second receiving-circuit terminal; a first diplexer disposed between the antenna terminal and the first transmission-reception switching circuit and between the antenna terminal and the second transmission-reception switching circuit; and a second diplexer connected to the second receiving-circuit terminal to selectively switch the signal transfer between the second receiving-circuit terminal and a third receiving-circuit terminal and the signal transfer between the second receiving-circuit terminal and a fourth receiving-circuit terminal by using a phase-shifting circuit and a surface-acoustic-wave filter.
