Paper Abstract

Conventional band-pass filter design is reviewed with respect to (non-radiative dielectric) NRD-guide technology and a new step-by-step method is proposed for the design of dual-path band-pass filter using small NRD guide resonator. A mode matching formulation, accounting for inherent higher- order modal coupling effects, is used to calculate the generalized S matrix of discontinuities encountered in all kind of filters, as well as to simulate the entire filters. Upon a reduction of the transfer function of the dual-path band-pass filter, a low-pass prototype network is obtained and calculated. Based on our mode-matching software tool, an iterative optimization process is then developed to design a filter with deep attenuation poles. A practical example is given and a short comparison with the conventional band-pass filter is made.
