本文介绍一种适合于微波超外差侦察系统和频谱分析系统作预选器和本振的YIG调谐滤波器一振荡器集成统调组件。该统调组件在S波段范围内,YIG滤波器的中心频率与YIG振荡器的振荡频率始终保持一固定频差的统调跟踪。在环境温度为-10～+55℃范围内,振荡器输出功率达到10mW以上,有效带宽可大于15MHz,失谐隔离大于60dB。该统调组件还具有体积小,使用方便,供电简单等优点。 This paper presents a YIG tuned filter-oscillator integrated monotone component suitable for use as pre-selector and local oscillator for microwave super-heterodyne reconnaissance and spectrum analysis systems. The tuning component in the S-band range, YIG filter center frequency and YIG oscillator oscillation frequency always maintain a fixed frequency offset tracking. In the ambient temperature range of -10 ~ +55 ℃, the oscillator output power of 10mW or more, the effective bandwidth can be greater than 15MHz, detuning more than 60dB isolation. The tuning component also has the advantages of small size, easy to use, simple power supply and so on.
