一种微波有源滤波器的实验研究

Experimental Study of A Microwave Active Filter

研究了一种利用耦合负阻法制作微波有源带通滤波器的方法。基于这种方法，制作了一个Ｃ波段的单级微带端耦合滤波器。实验结果表明，利用耦合负阻到谐振腔的方法，可明显改善滤波器的通带特性。

A coupled negative resistance method for building the microwave active band-pass filters is described in this paper.Based on this method, a C-band single stage microstrip line end-coupled filter has been designed and fabricated.Experimental results show that the method of coupling negative resistance to resonators can improve passband performance significantly.
