| 摘 要： | 本文给出一组全极点等电感带通滤波器设计公式,从归一化的低通原型直接获得等电感的归一化带通滤波器。与耦合谐振器窄带滤波器的近似设计方法不同,这是严格的变换。同时也给出实际电感偏离等电感的设计值时,修正电容及负载的计算公式。

| Abstract: | This paper presents a set of design formulae for all-pole bandpass filter with equal inductances.By rising this simple method,the bandpass filter can be obtained from normalized prototype lowpass filter immediately,In contrast with coupled- resonator bandpass filter,the responses of the filter remain the geometric symmetry strictly.In addition,design formulae for modification of capacitances and termin- ated resistances are also presented,which are used for compensating the inductor tolerances in practice. |
