摘要

提出了一种紧凑的四极可调滤波器,具有较好的阻带抑制能力。采用三个组合谐振器,相邻谐振器和非相邻谐振器之间通过调节变容实现耦合。结果表明,在非相邻耦合路径下,通带两侧存在两个传输零(共四个),因此阻带抑制能力显著提高。这种非相邻耦合也为通带响应提供了一个额外的极点。通过改变耦合值,可以控制传输零点和通带带宽的位置。演示了一种640- 1030mhz的可调谐滤波器,具有8-12%的可控带宽和宽阻带区域。应用领域是现代多标准通信系统。

A 640–1030 MHz four-pole tunable filter with improved stopband rejection and controllable bandwidth and transmission zeros
A compact 4-pole tunable filter with improved stopband rejection is presented. Three combline resonators are employed, and the coupling between the adjacent and non-adjacent resonators are achieved by tuning varactors. It is shown that with the non-adjacent coupling path, two transmission zeroes at both sides of the passband (totally four) are present, and therefore the stopband rejection is significantly improved. This non-adjacent coupling also contributes one additional pole to the passband response. The positions of the transmission zeroes and passband bandwidth are controllable by changing the coupling values. A tunable filter at 640-1030 MHz is demonstrated with a controllable bandwidth of 8-12% and a wide stopband region. The application areas are in modern multi-standard communication systems.
