Simulation and realization of solid-state electrically tuning filters

Макет 3-резонаторного перестроюваного фільтра з напівпровідниковими варикапами

The solid-state electrically tuning filters are main elements of different multifrequency communication systems with high reliability. New approach to designing electrically tuned band-pass filters that is based on use U-shaped microstrip resonators with several varactors connected to each resonator is proposed. This approach allows to creating prototypes which exceeds world level of varactor-tuned filters.
