Abstract

Summary form only given, as follows. A compact, 35-GHz, phase-locked gyrotron oscillator operating at a harmonic of the cyclotron frequency is under development. It will be compatible with the requirements of airborne and vehicular millimeter-wave radars. The gyrotron is characterized by three unique features: (1) a novel complex cavity with superior mode selection and high power handling capabilities: (2) subharmonic frequency injection, where the phase of the output radiation will be controlled by a small input signal at subharmonic frequency; and (3) low magnetic field requirements compatible with modern permanent magnet technology (Nd/Fe/B). The gyrotron is designed for operation at 35 GHz with peak output power of ~150 kW and efficiency of 30%. A phase locking gain of about 50 dB at the second and third harmonics is expected
