Annotation: The article discusses the method of improving the stability of the YIG filter frequency setting. This method is based on thermal stabilization of the filter corps by means of the Peltier and microwave camera by means the resistive heaters. Hysteresis in filter is described and new tuning control algorithm that minimized the hysteresis effect is proposed.
