Classification: CPC H | IPC H

Claim 3:
4. A transceiver circuit comprising:
a Doherty amplifier including a main amplifier and a peak amplifier;
a low noise amplifier; and
an antenna switch configured to selectively connect the Doherty amplifier and the low noise amplifier to an antenna port,
wherein the Doherty amplifier is configured to operate in an envelope tracking (ET) mode and a Doherty mode, the ET mode being a mode in which the main amplifier and the peak amplifier operate as envelope tracking amplifiers, the Doherty mode being a mode in which a first bias current supplied to the peak amplifier is less than a second bias current supplied to the main amplifier.
