【摘要】 分析研制了一种反射式腔稳双变容管调谐的毫米波耿氏振荡器,近(?)频相位噪声为-60dBc/Hz(f_m=1kHz);-95dBc/Hz(f_m=50kHz),粗(?)谐为10～20MHz/(0～15)V,细调谐为±1～±3MHz/(0～15)V,而且细(?)谐极性可变.并已成功地应用于毫米波系统中.更多还原

【Abstract】 The analysis and design of a new-type MM-wave VCO, reflection-type cavitystabilized, double varactors tuned Gunn oscillator are presented in this paper. The per-formances of the VCO are: phase noise: -60dBc/Hz(f_m=1kHz), -95dBc/Hz (f_m=50kHz); rough tuning: 10~20MHz/(0~15)V; fine tuning:±(1~3) MHz/(0~15)V. The newtype VCO has been successfully applied in a MM-wave Doppler pulse radar.更多还原
