Abstract
A Doherty amplifier according to the present disclosure includes an input terminal, an output terminal, a carrier amplifier connected between the input terminal and the output terminal, a peak amplifier connected in parallel to the carrier amplifier between the input terminal and the output terminal, a first input matching circuit connected between the input terminal and the carrier amplifier and a second input matching circuit connected between the input terminal and the peak amplifier, wherein the carrier amplifier and the peak amplifier output signals toward outside in directions opposite to each other.
Claims10
A Doherty amplifier comprising:
- an input terminal;
- an output terminal;
- a carrier amplifier connected between the input terminal and the output terminal;
- a peak amplifier connected in parallel to the carrier amplifier between the input terminal and the output terminal;
- a first input matching circuit connected between the input terminal and the carrier amplifier;
- and
- a second input matching circuit connected between the input terminal and the peak amplifier,
- wherein an output of the carrier amplifier faces a first direction away from the first input matching circuit and an output of the peak amplifier faces a second direction away from the second input matching circuit, and
