Abstract
An electronic device includes: at least one antenna; and a power amplifier electrically connected to the at least one antenna. The power amplifier includes: a first amplification circuit; a first transformer; a first switch; a second amplification circuit; a second transformer; a second switch; the power combiner; and the third switch configured to electrically connect at least one of the first switch, the second switch, or an output port of the power combiner with the at least one antenna.
Claims20
An electronic device comprising:
- at least one antenna;
- and
- a power amplifier electrically connected to the at least one antenna,
- wherein the power amplifier comprises:
- a first amplification circuit disposed on a first electrical path between a first input port of the power amplifier and the at least one antenna, the first amplification circuit being configured to amplify a first signal provided through the first input port and to output a first output signal;
- a first transformer disposed on the first electrical path between the first amplification circuit and the at least one antenna;
- a first switch disposed on the first electrical path between the first transformer and the at least one antenna, the first switch being configured to electrically connect the first transformer with a third switch or a power combiner;
- a second amplification circuit disposed on a second electrical path between a second input port of the power amplifier and the at least one antenna, the second amplification circuit being configured to amplify a second signal provided through the second input port and to generate a second output signal;
- a second transformer disposed on the second electrical path between the second amplification circuit and the at least one antenna;
- a second switch disposed on the second electrical path between the second transformer and the at least one antenna, the second switch being configured to electrically connect the second transformer with the third switch or the power combiner;
- the power combiner configured to combine power of the first output signal provided from the first transformer through the first switch and power of the second output signal provided from the second transformer through the second switch and to generate a third output signal;
- and
- the third switch configured to electrically connect at least one of the first switch, the second switch, or an output port of the power combiner with the at least one antenna.
