摘　　要：介绍了一种工作在微波频段的可重构滤波器,其中心工作频率(f_(0))与瞬时带宽(Δf)均可调节。实现方法是基于YIG磁调谐带通滤波器工作频率可连续调节的特性,采用两组级联谐振子,通过其工作频率的同向或反向同步调节可分别实现f_(0)与Δf一定范围内的调节。原理样机主线圈控制f_(0)调节,实现f_(0)调节范围4~6 GHz,副线圈控制Δf调节,实现Δf调节范围30~80 MHz。试验结果表明,基于YIG滤波器的双调模型具有一定的实用性,对YIG磁调滤波器多维度指标重构的发展有借鉴作用。This article introduces a reconfigurable filter working in the microwave frequency band,the center operating frequency(f_(0))and instantaneous bandwidth(Δf)can be adjusted,and the implementation method is based on the continuous tuning of working frequency of the YIG-tuned band-pass filter.Double-adjusting of working frequency in the same or reverse direction of the two sets of cascaded harmonic oscillators can respectively realize the adjusting of f_(0) andΔf within a certain range.The main coil of principle prototype controls f_(0) in the range of 4-6 GHz,and the secondary coil controlsΔf in the range of 30-80 MHz.The experimental results show that the double-adjusting model based on YIG filter has certain practicality,which has a reference for the development of multi-dimensional index reconstruction of YIG-tuned filter.
