Classification: CPC H | IPC H

Claim 8:
9. A transceiver circuit comprising:
a Doherty amplifier including a main amplifier and a peak amplifier;
a low noise amplifier;
a first band pass filter connected between an output of the Doherty amplifier and an antenna port;
a second band pass filter connected between an input of the low noise amplifier and the antenna port; and
an antenna switch configured to connect the first band pass filter or the second band pass filter to the antenna port, wherein
the Doherty amplifier is configured to operate in an envelope tracking (ET) mode and a Doherty mode, the Doherty mode being a mode in which the main amplifier operates and the peak amplifier does not operate before an output power level of the main amplifier approaches a saturation level and both of the main amplifier and the peak amplifier operate after the output power level of the main amplifier approaches the saturation level.
