Abstract
A high-frequency circuit includes an amplifier, a power distributor disposed on an output route of the amplifier, a first by-pass route that bypasses the amplifier, a second by-pass route that bypasses the power distributor, a first switch and a second switch disposed in series on the first by-pass route, and a third switch disposed in series on the second by-pass route. The first by-pass route is connected to a first node on a route connecting a signal input terminal and the amplifier and a second node on a route connecting the amplifier and the power distributor. The second by-pass route is connected to a third node between the first switch and the second switch and a fourth node on an output route of the power distributor.
Claims15
A high-frequency circuit comprising:
- a signal input terminal;
- an amplifier configured to amplify high-frequency signals input at the signal input terminal;
- a power distributor that is in line with an output path of the amplifier and that is configured to perform power distribution on high-frequency signals;
- a first by-pass path that bypasses the amplifier and that is configured to transmit high-frequency signals;
- a second by-pass path that bypasses the power distributor and that is configured to transmit high-frequency signals;
- a first switch and a second switch that are in line with the first by-pass path and that are configured to selectively allow transmission of high-frequency signals through the first by-pass path;
- and
- a third switch that is in line with the second by-pass path and that is configured to selectively allow transmission of high-frequency signals through the second by-pass path,
- wherein the first by-pass path is connected to a first node on a path connecting the signal input terminal to an input terminal of the amplifier, and a second node on a path connecting an output terminal of the amplifier to an input terminal of the power distributor, and
- wherein the second by-pass path is connected to a third node that is between the first switch and the second switch and that is on the first by-pass path, and a fourth node on an output path of the power distributor.
