Various coherent power combining schemes have been developed with high power magnetrons to meet the increasing industrial demands of HPM and Wireless Power Transfer applications.In this paper, we propose a power combining scheme for two 1.25 kW magnetrons, based on phase‐shifter less philosophy. The proposed scheme utilizes a single signal generator synthesizing the injection signal for both magnetrons. A single RF Power Amplifier (PA) amplifies the injection signal for both magnetrons to the power level required by Adler's criteria. The amplified signal is then divided by 2:1 RF power divider. The divided signals are subsequently used for injection locking of both magnetrons through same length coaxial cables. The output power of the two magnetrons is combined in a symmetric H‐plane T‐combiner. Since both magnetrons follow the phase of a common injection source the instantaneous phase deviation in their injection‐locked responses is minimal, leading to a combining efficiency of 95%.
