Abstract
Provided is an amplification circuit that includes: a low-noise amplifier that includes an FET as an amplification element and that amplifies a radio-frequency signal inputted to the gate of the FET; an input matching network that matches the input impedance of the low-noise amplifier; and a switch that is serially connected between ground and a node on a line connecting the input matching network and the gate of the FET to each other.
Claims12
An amplification circuit comprising:
- a first amplifier that comprises a field effect transistor (FET) as an amplification element, and that is configured to amplify a radio-frequency (RF) signal input to a gate of the FET;
- an input matching network configured to match an input impedance of the first amplifier;
- and
- a switch that is serially connected between ground and a node on a path connecting the input matching network and the gate to each other.
