Abstract

A Doherty amplifier includes a carrier amplifier including a first FET, the first FET having a plurality of gate electrodes, and a peaking amplifier including a second FET, the second FET having a plurality of gate electrodes, a gate-to-gate interval of the gate electrodes of the second FET being shorter than a gate-to-gate interval of the first FET.
