Abstract: The present disclosure provides methods for manufacturing Doherty power amplifiers. The methods include: providing at least one main amplifier operated at a fundamental frequency; providing at least one peaking amplifier connected to the main amplifier in parallel and sharing a common load or a load; and connecting a first hybrid integrated matching circuit between output terminals of the at least one main amplifier and the at least one peaking amplifier. Connecting the first hybrid integrated matching circuit includes connecting a first circuit between the output terminals of the at least one main amplifier and the at least one peaking amplifier. The first circuit contributes as a part of an impedance inverting network of the first hybrid integrated matching circuit of the Doherty power amplifier.
