Abstract
An electronic device includes a communication circuit. The communication circuit includes at least one receive amplifier configured to connect to an antenna and to low-noise amplify at least a part of a multi-band signal, and a transceiver including a mixer configured to mix the signal low-noise amplified by the at least one receive amplifier, wherein the transceiver is configured to process the multi-band signal.
Claims19
A communication circuit comprising:
- an antenna;
- and
- a radio frequency (RF) module comprising:
- a transmit amplifier configured to amplify a signal output from a transceiver;
- a front-end switching circuit configured to connect to the antenna;
- a duplexer or a quadplexer configured to be disposed between the front-end switching circuit and the transmit amplifier;
- at least one back-end switching circuit coupled to the duplexer or the quadplexer;
- and
- at least one receive amplifier that is disposed between the at least one back-end switching circuit and the transceiver,
- wherein the at least one receive amplifier is configured to low-noise amplify at least a part of a multi-band signal, and
- wherein the transceiver comprises a mixer configured to mix the multi-band signal low-noise amplified by the at least one receive amplifier.
