Abstract
It is demonstrated that injection-locked magnetrons can be used to drive a moderate Q cavity without a circulator with excellent interpulse phase coherency. A 3-dB hybrid coupler provides the avenue for both injection locking and power combining of magnetron pairs. Better intrapulse phase coherency than has been demonstrated is anticipated when lower Q magnetrons or lower gains are used. The cavity transient impedance does not preclude the magnetrons from filling the cavity, at least when the cavity fill time is less than the magnetron phase lock time.<>
