依据电调基频、提取谐波的构想，建立了串联型宽带变容管电调谐波振荡器的电路模型。在３ｍｍ频段上完成了电路设计，获得了１５％的相对电调带宽，带内最小功率５ｍＷ，最大功率超过１７ｍＷ；输出功率大于５ｍＷ的电调带宽达到１３ＧＨｚ。以宽带电调谐波振荡器为核心，完成了３ｍｍ电调信号源的系统设计，该信号源工作带宽１０ＧＨｚ，频率显示误差小于１００ＭＨｚ，频率稳定度（２～９）×１０－４／ｈ，可以连续波和方波两种方式工作
Based on the idea of adjusting the fundamental frequency and extracting the harmonics, a circuit model of a series broadband varactor tuned oscillator has been established. The circuit design was completed in the 3mm band, achieving a relative electrical transfer bandwidth of 15% with a minimum in-band power of 5mW and a maximum power of more than 17mW and an ESC bandwidth of over 5mW to 13GHz. The system design of 3mm electric signal source is completed with broadband tuned oscillator as the core. The working bandwidth of this signal source is 10GHz, the error of frequency display is less than 100MHz, the frequency stability is 2 ~ 9 × 10-4 / h, Can be continuous wave and square wave two ways to work
