Embodiments described herein relate to a Doherty amplifier. The Doherty amplifier may include a main amplifier and a first peak amplifier, a second peak amplifier, and a third peak amplifier, each amplifier having an input and an output. The Doherty amplifier may also include a combining network configured for combining signals emerging at outputs of the amplifiers. The signals are combined at a combining node. The combining network includes a first impedance inverter arranged in between the output of the main amplifier and the output of the third peak amplifier. The combining network also includes a second impedance inverter arranged in between the output of the first peak amplifier and the output of the second peak amplifier. The combining network also includes a first 180 degrees phase shifter and a second 180 degrees phase shifter. Additionally, the combining network includes a third impedance inverter.
