Abstract
A Doherty power amplifying apparatus includes a harmonic-controlled Doherty amplifier; and an input matching unit and an output matching unit for input matching and output matching the harmonic-controlled Doherty amplifier, respectively. The harmonic-controlled Doherty amplifier includes a carrier amplifier; a peaking amplifier arranged in parallel to the carrier amplifier; and a harmonic control circuit, arranged in front of the output matching unit, for controlling a harmonic component of an output of the Doherty amplifier to enable the Doherty amplifier to perform a switching or saturation operation.
