In orthogonally polarized H(11)° Multi-mode circular waveguide systems,filtration of several lower high-order modes such as E(01)° E(11)° has been treated favorably. However, no report on further research in the filtration of higher-order modes such as H(21)° has so far been revealed. In this paper, operational principle and design scheme of an H(21)° mode filter are dealt with, approximate formula for determining mode coupling quantities according to Bethe's small Holes diffraction theorems is derived, and...

In orthogonally polarized H(11)° Multi-mode circular waveguide systems,filtration of several lower high-order modes such as E(01)° E(11)° has been treated favorably. However, no report on further research in the filtration of higher-order modes such as H(21)° has so far been revealed. In this paper, operational principle and design scheme of an H(21)° mode filter are dealt with, approximate formula for determining mode coupling quantities according to Bethe's small Holes diffraction theorems is derived, and methods for compu-ting mode attenuations for cascaded multicavity filter and reflection characteristics of dominant mode are proposed. Experimental results have checked well with the theoretical analysis and design formulas; the transmission characteristics of the dominant and higher-order modes are perfectly satisfactory.

在具有正交极化H_(11)°波多模圆波导系统中,H_(21)°波的滤除问题至今未见有较重大的进展。本文提出了一种关于波型滤波器的工作原理和设计方案,并根据Bethe小孔绕射理论导出了波型耦合量的近似计算公式,给出了连级多腔滤波器的波型衰耗和主波反射特性的计算方法。实验证实了理论分析和设计的正确性。波型滤波器的主波和高次波型传输特性得到了比较满意的结果。

In the cascade realization of high order active filters, the sequence of cascading is based on the considerations of maximum dynamic range and signal to noise ratio. To determine the optimum sequence, the classical method requires cumbersome and tedious calculations. Simpler methods were suggested, but were not proved very satisfactory in practive. Here we present a new method for the arrangement, and through an example of the computation of a tenth order elliptical band-pass filter, show its validity and versatility....

In the cascade realization of high order active filters, the sequence of cascading is based on the considerations of maximum dynamic range and signal to noise ratio.

Here we present a new method for the arrangement, and through an example of the computation of a tenth order elliptical band-pass filter, show its validity and versatility.

高阶有源滤波器级联实现时,各级顺序的安排,是从动态范围最大和信噪比最大出发考虑的。决定顺序的安排,过去已有的方法,需要繁复的计算。阶数高时,计算量更为可观。也有人提出过简单的安排方法,但实践证明,并不恰当。本文提出新的安排方法,简单而符合实际,并通过一个十阶带通椭圆型滤波器的计算,作为例子,说明这种方法的依据。

Higher order modes coupling characteristics in H_11~°, circular bending waveguide are analyzed according to the coupled wave equations, and coupling coeffecients of E_01~°, H_21~°, modes and their amplitudes are computed. A broad-band H_21~°, E_01~° mode filter has been presented. Experimental results indicated that its practical application is quite satis-factory. Thus, the problems presented by N. Nakajima, etc. can be solved.

近年来,N.Nakajima等对4、5、6GHz共用天线波导系统中一种高性能偏置激励的卡塞格伦微波天线所用多模圆弯曲波导的传输特性及其高次波型E_(01)~O的影响进行了分析和实验研究,而文中对弯波导所激发的另一重要高次波型H_(21)~O的影响和有效地处理方法并未解决。本文根据任意截面弯曲波导耦合波方程组分析并计算了H_(11)~O多模圆弯曲波导内高次波型耦合特性及其前两个最重要的较低阶高次波E_(01)~O、H_(21)~O的耦合系数和波型激发量,提出了一种宽频带H_(21)~O、E_(01)~O波型滤波器,实验表明波型滤波器的实用效果良好,从而使N.Nakajima等遇到的并待克服的问题可基本解决。
