Abstract: The present invention relates to a Doherty power amplifier, and a Doherty power amplifier module configured to be mounted on a printed circuit board for forming such a Doherty power amplifier. According to the present invention, a series network of a shunt inductor and shunt DC decoupling capacitor is used to partially resonate out the output capacitance of the main transistor. In addition, a series inductor is connected in between the output of the main transistor and the combining node, and a shunt capacitive element is connected in between the combining node and ground. The part of the output capacitance that is not resonated out, the series inductor, and the shunt capacitive element form a lumped equivalent of a 90 degrees transmission line at the fundamental frequency.
