一种具有广义切比雪夫响应的新型宽带高通滤波器

A Novel Broadband High-Pass Filter with Generalized Chebyshev Response

小型化伪高通滤波器具有高带外抑制,在性能和尺寸上相比传统结构具有优势。枝节线高通滤波器具有频带宽和结构简单的特点,但是带外抑制较差。采用在传统枝节线高通滤波器中引入非相邻节耦合的方式,在大幅提高滤波器带外抑制的同时实现小型化。

A miniature pseudo-high-pass filter with high out-of-band suppression is intro-duced.The branch-line high-pass filter has the characteristics of frequency bandwidth and sim-ple structure,but the out-of-band suppression is poor.By combining a non-adjacent node cou-pling with the traditional branch-line high-pass-filter,great improvements can be made on the out-of-band suppression.Due to the compact structural arrangement,miniaturization and high performance is also achieved.
