本文给出微带抽头耦合交指滤波器的一种新设计方法。这种方法的特点是能够根据设计的需要合理调整各谐振器的导纳值,适用于计算机程序设计。制作的滤波器具有低的通带损耗和优良的阻带衰减特性。并且滤波器适用印制板工艺加工,成本很低。
In this paper, a new design method of microstrip tap coupling interdigital filter is given. This method is characterized by the need to properly adjust the admittance of each resonator, suitable for computer programming. The fabricated filter has low passband loss and excellent stopband attenuation characteristics. And filter for PCB processing, low cost.
