摘要： A small-sized switch apparatus for switching between signal paths of at least first, second and third frequency bands is capable of handling high-powered high-frequency signals with a relatively low control voltage and is useful in a mobile terminal apparatus. A first signal terminal of a diplexer is connected to an antenna terminal, and a second signal terminal is connected to a high-frequency switch via a filter. A third signal terminal of the diplexer is connected to a high-frequency switch via a second filter. The high-frequency switch has PIN diodes as switching devices, and performs switching between a global system for mobile communications transmission signal and a global system for mobile communications reception signal. The high-frequency switch has three sets of serially connected multi-staged FETs as switching devices, and performs switching between wide-band code division multiple access transmission/reception signals, a digital cellular system transmission signal and a digital cellular system reception signal.
