摘　　要：本文描述一种六毫米波段注入锁定振荡器.该振荡器由耿管振荡器、环行器、锁相参考源组成,耿管振荡器采用背腔式稳频和谐振帽电路结构,输出端经环行器与高稳定度锁相源连接.注锁振荡器的输出功率大于60mW,振荡频率为46.1GHz,偏离载频10kHz处,单边带(SSB)相位噪声≤-71.7dBc/Hz,杂波≤-40dB.Presented in this paper are the configuration and performances of a Q-band injection-locked Gunn oscillator with its output connected to a phase-locked reference source by a circulator. The output power of the oscillator is more than 60mW at 46.1GHz. The single-sideband (SSB) phase noise is less than - 71. 7dBc/Hz at 10kHz offset from the carrier, and the spectrum of spurious signal is less than -40dB.
