    摘要： A switch circuit is provided with a plurality of MEMS switches, which have different drive voltages and are connected parallel or in series, and a single voltage supply for driving the MEMS switches by the plurality of drive voltages. The switch circuit is used for a microwave circuit and an antenna circuit, and the configurations of the microwave circuit and the antenna circuit are varied by the drive voltage value. Namely, the configurations of the microwave circuit and the antenna circuit can be varied by the drive voltage value by using the switch circuit composed of the MEMS switches having the different drive voltages for the microwave circuit and the antenna circuit.

    摘要翻译： 开关电路设置有多个具有不同驱动电压并且并联或串联连接的MEMS开关以及用于通过多个驱动电压来驱动MEMS开关的单个电压源。 开关电路用于微波电路和天线电路，并且微波电路和天线电路的配置根据驱动电压值而变化。 即，微波电路和天线电路的配置可以通过使用由具有用于微波电路和天线电路的不同驱动电压的MEMS开关构成的开关电路而由驱动电压值改变。
