    摘要: There is provided a variable power distributor capable of calculating an error between transmission lines of two systems after building a variable power distributor and correcting the set value of the amplitude/phase according to the error. An error detection method for this and a set value correction method are also disclosed. The variable power distributor includes: a two-way distributor arranged at the input side of a pair of transmission lines consisting of a first and a second transmission line; a 90-degree hybrid circuit arranged at the output side of the pair of transmission lines; and a variable phase device, variable resistance attenuator, and a power amplifier which are arranged at each of the pair of the transmission lines between the two-way distributor and the 90-degree hybrid circuit. The variable power distributor further includes error detection means for monitoring an output signal from the 90-degree hybrid circuit and detecting an error existing in each component between the first and the second transmission line according to the monitor output.

    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.
