Abstract
A high-frequency circuit includes a transmission circuit that transmits a high-frequency signal, a reception circuit that receives a high-frequency signal, and a multiplexer that separates a reception path and a transmission path for high-frequency signals. In the reception circuit, a filter circuit in which a first frequency response and a second frequency response different from the first frequency response can be switched in accordance with a jamming wave for a high-frequency signal to be received is provided in the reception path for a high-frequency signal.
