Patent attributes
A high-frequency circuit includes a first signal path transmitting a high-frequency signal in a first frequency band group, a second signal path transmitting a high-frequency signal in a second frequency band group, a switch including a common terminal and selection terminals, a first low noise amplifier including an input terminal connected to the first signal path and an output terminal connected to a first selection terminal, a second low noise amplifier including an input terminal connected to the second signal path and an output terminal connected to a second selection terminal, and an output-side impedance matching circuit that matches impedance at the output side of the first low noise amplifier or impedance at the output side of the second low noise amplifier with a predetermined impedance with a conductive state between the a third selection terminal and the common terminal.
