Abstract
An amplifier according to an embodiment of the present disclosure includes a first transistor and a first matching circuit. The first matching circuit is connected between an input terminal and a control terminal of the first transistor. The first matching circuit includes a first inductor, a second inductor, and a first switch. The first inductor has an end connected to the control terminal. The second inductor has an end connected to the other end of the first inductor. The first switch is configured to selectively switch between electrical continuity between the input terminal and the other end of the first inductor and electrical continuity between the input terminal and the other end of the second inductor.
Claims8
An amplifier having an input terminal and an output terminal, for amplifying a signal input from the input terminal and outputting an amplified signal from the output terminal, comprising:
- a first transistor including a control terminal, a first terminal, and a second terminal;
- and
- a first matching circuit connected between the input terminal and the control terminal of the first transistor, wherein
- the first terminal of the first transistor is connected to a ground,
- the second terminal of the first transistor is connected to a power supply and the output terminal, and
- the first matching circuit comprises:
- a first inductor having a first end and a second end, the first end of the first inductor being connected to the control terminal,
- a second inductor having a first end and a second end, the first end of the second inductor being connected to the second end of the first inductor, and
- a first switch configured to selectively connect the input terminal to the second end of the first inductor or the second end of the second inductor.
