摘要
本文提出了一种新型的可调谐带通滤波器。这款带通滤波器由两个双谐振环谐振器和一对L型耦合臂组成。通过在谐振器中加入PIN二极管,于谐振器中引入可控微扰,使得谐振器的频率切换,实测其通带可实现从2.11GHz至2.22GHz到2.32GHz至2.49GHz的切换。本文对一个二阶的可调谐滤波器做了加工,结果与仿真相吻合。
A new type of tunable band-pass filter is presented in this paper. This band pass filter consists of two SRR resonators and a pair of enhanced L-shaped coupling arms. Controllable perturbations are introduced into the resonator by loading a p-i-n diode inside the resonator so that resonate frequency can be switched. The proposed tunable filter can switch between passband of 2.11 GHz to 2.22 GHz and passband of 2.32 GHz to 2.49 GHz.The fabrication of a second-order tunable filter is carried out to verify the simulation.
