Controlled Harmonic Frequency Locking in the Harmonic Recirculating Planar Magnetron

Abstract

The Harmonic Recirculating Planar Magnetron (HRPM) is a variant of the Recirculating Planar Magnetron (RPM) [1] intended for generation of two or more frequencies simultaneously. Building on the Multi-Frequency Recirculating Planar Magnetron (MFRPM) [2], the HRPM modifies the planar geometry by placing an upstream L-Band Oscillator (LBO at ∼1 GHz) and downstream S-Band Oscillator (SBO at ∼2 GHz) on the same side of the cathode. The HRPM is a proof-of-principle magnetron prototype with the potential of generating four or more frequencies.
