Abstract
An electronic device may include a communication processor, a transceiver, an antenna, a power supply module, and a communication circuit. The communication circuit includes an input terminal configured to acquire a signal transmitted from the transceiver, an amplifier module, an output terminal configured to transmit a signal to the transceiver, an antenna terminal connected to the antenna, a first switch connected to the input terminal and the amplifier module, a second switch connected to the amplifier module and the output terminal, and a third switch connected to the first switch, the second switch, and the antenna terminal.
Claims12
An electronic device comprising:
- a communication processor;
- a transceiver;
- an antenna;
- a power supply module;
- and
- a communication circuit operatively connected to the communication processor,
- wherein the communication circuit comprises:
- an input terminal configured to acquire a signal transmitted from the transceiver;
- an amplifier module configured as a single component, the amplifier module comprising:
- a first amplifier group including at least one drive amplifier configured to amplify the signal from the transceiver, and
- a second amplifier group including at least one power amplifier connected to the at least one drive amplifier and configured to amplify a signal from the first amplifier group;
- an output terminal configured to transmit a signal from the communication circuit to the transceiver;
- an antenna terminal connected to the antenna;
- a first switch connected to the input terminal and the amplifier module;
- a second switch connected to the amplifier module and the output terminal;
- and
- a third switch connected to the first switch, the second switch, and the antenna terminal,
- wherein the communication processor is configured to:
- control the first switch, the second switch, and the third switch to connect the at least one drive amplifier and the at least one power amplifier to the antenna during transmission mode, and to connect the at least one power amplifier to the antenna without connection with the at least one drive amplifier during reception mode such that a power gain during the transmission mode is higher than a power gain during the reception mode.
