摘要：A circuit selection device includes a first terminal, a plurality of transmissionlines, a plurality of second terminals, a plurality of loads for impedance matching, and aplurality of switches. An RF signal is input/output to/from the first terminal. Eachtransmission line has one end connected to the first terminal. Each of the secondterminals is arranged in correspondence with the other end of each of the transmissionlines to selectively input/output an RF signal input/output to/from the first terminal. Eachload is arranged in correspondence with the other end of each of the transmission lines.Each switch is switched/connected to one of the second terminal and the load whichcorrespond to the other end of each of the transmission lines. When one of the switchesis switched to the second terminal side, the remaining switches are switched to the loadside.
