Abstract

A novel quasi-elliptic balanced bandpass filter (BBPF) designed on microstrip technology that uses Asynchronously Coupled Dual-Mode Resonator (ACDMR) is proposed. The filter is based on a novel Balanced Asynchronous Box (Basybox), which has five couplings and three resonators (two λ/2 resonators and a dual-mode grounded λ/2 resonator). By changing a conventional triplet with the use of dual-mode resonators, we can generate a non-resonant mode that generates a transmission zero (TZ). In addition, the filter has a balanced response. In this paper, full design methodology is presented along with a practical implementation. The filter has a center frequency in differential-mode of 950 MHz, a bandwidth of 53 MHz and a transmission zero at 975 MHz. For the common-mode, there is a rejection higher than 15 dB throughout the band up to 3 GHz. Good agreement between simulation and measurement is observed.

采用异步耦合双模谐振器设计具有一个传输零的平衡带通滤波器

提出了一种基于微带技术、采用异步耦合双模谐振腔的准椭圆平衡带通滤波器(BBPF)。该滤波器基于一种新型的平衡异步盒(Basybox)，它有五个耦合和三个谐振器(两个λ/2谐振器和一个双模接地λ/2谐振器)。通过使用双模谐振器改变传统的三重态，我们可以产生产生传输零(TZ)的非谐振模式。此外，该滤波器具有平衡的响应。在本文中，提出了完整的设计方法以及实际实现。该滤波器的差模中心频率为950 MHz，带宽为53 MHz，传输零点为975 MHz。对于共模，在3ghz以内的整个频段内，抑制值高于15db。仿真结果与实测结果吻合良好。
