Presented in this paper is the design and performance of a C band high frequency-stability broad-band FET voltage-controlled oscillator (VCO) consisting of an oscillating FET and a GaAs electrically tunned varactor with constant y as well as a constant temperature-controlled circuit. The VCO provides an output power of greater than 30mW, a power flatness of better than 1dB and a frequency stability of 10-5 at 4-6-8GHz through reasonable design.

本文叙述了用场效应振荡管和砷化镓常γ电调变容二极管及恒温控制电路等构成的C波段高频率稳定度宽带场效应管电压控制振荡器(VCO)的设计和电性能.通过合理的设计,VCO在4~6~8GHz的频率范围内,得到输出功率大于30mW,功率平坦度小于1dB,频率稳定度在10~(-5)量级.

To realize low frequency drift in oscillator circuits,constant temperature controlled circuit for temperature compensation is adopted.In structure designing,partial constant temperature to packaged integrated VCO is employed,instead of constant temperature tank structure.The key factors influenced on frequency drift are introduced.With logical design,we obtained expected specification and realized miniaturization.

采用附加恒温电路对振荡器进行温度补偿 ,进而实现了低温漂。在结构设计上摒弃了传统的复杂恒温槽结构 ,改为对管壳封装的集成 VCO进行局部恒温 ,讨论了对温度漂移有影响的关键因素。通过合理设计 ,达到了要求的技术指标 ,实现了小型化。
