Abstract :
The design of a five-pole in line elliptic filter using TEl13 and TM012 modes presented. Simultaneous TE/TE and TE/TM mode coupling between the dual and the triple mode cavities is provided by a single displaced rectangular iris. In the present work, the modelling of the discontinuities is based on a variational integral multimodal method. This rigorous and accurate method allows to determine the optimum iris dimensions and position which ensure both required couplings. The response of a designed filter (central frequency 10 GHz and bandwidth 40 MHz) will be presented.
