Claim 0:
1. 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;
an antenna switch configured to connect the first band pass filter to the antenna port during a transmission connection state in which a first signal output from the Doherty amplifier is supplied to the antenna port, and to connect the second band pass filter to the antenna port during a reception connection state in which a second signal received by the antenna port is inputted to the low noise amplifier; and
a control circuit that is configured to control an operation of the Doherty amplifier by switching an operation mode of the Doherty amplifier between an envelope tracking mode and a Doherty mode.
