Abstract:
A high frequency variable attenuation circuit includes an input terminal, an output terminal, a first resistor, a second resistor, a third resistor, and a first switching circuit. The first switching circuit has an output side resistor and an output side switching element that are connected in series to each other. The first switching circuit has a first circuit end connected to the second end of the second resistor and the output terminal, and a second circuit end connected to the ground.
