In this article, the complete theoretical analysis of a Doherty amplifier employing a Class AB bias condition for the Main and a Class C one for the Auxiliary devices, respectively, is presented. Starting from the simplified model of an active device, the analysis of the AB-C Doherty behavior is car

## Abstract A Doherty amplifier is described in which odd harmonics from the class‐C peaking amplifier flow to the main amplifier to achieve class‐F operation, without the need for complicated space consuming harmonic control circuits. The measured efficiency exceeded 50% above the 6 dB back‐off. T
