AMPLIFIER CIRCUIT, ANTENNA MODULE AND WIRELESS COMMUNICATION APPARATUS |
| 摘要 |
An amplifier circuit that amplifies a carrier wave that a transmitting and receiving part has received, and includes a superimposition wave generation part that generates a superimposition wave to be superimposed onto the carrier wave; an amplifying part that adds the carrier wave and the superimposition wave to obtain an amplified carrier wave and outputs the amplified carrier wave; and an amplitude detection part that detects, based on a change in an amplitude value of the carrier wave, that the carrier wave is a predetermined carrier wave that carries a predetermined communication signal. The amplifier circuit outputs the amplified carrier wave when having detected the predetermined carrier wave. |

1. An amplifier circuit that amplifies a carrier wave that a transmitting and receiving part has received, the amplifier circuit comprising:
a superimposition wave generation part that generates a superimposition wave to be superimposed onto the carrier wave; an amplifying part that adds the carrier wave and the superimposition wave to obtain an amplified carrier wave, and outputs the amplified carrier wave; and an amplitude detection part that detects, based on a change in an amplitude value of the carrier wave, that the carrier wave is a predetermined carrier wave that carries a predetermined communication signal, wherein the amplifier circuit outputs the amplified carrier wave when having detected the predetermined carrier wave. |
