Popis: Efficient mode-matching waveguide building blocks are described for user-friendly utilization in common commercial circuit CAD tools. This hybrid mode-matching/circuit theory CAD approach allows the accurate, convenient, and fast design of a comprehensive class of rectangular and/or circular waveguide components, such as filters, transformers, and multiplexers by advantageously combining the accuracy of the rigorous electromatic simulators with the efficiency of mature and well-established circuit theory design instruments. Moreover, an adequate multimode combination technique between the individual elements enables the utilization of additional design parameters resulting from higher-order mode interaction effects. The efficiency of the hybrid CAD method is demonstrated at typical microwave design examples that are optimized by use of the mode-matching waveguide building blocks in powerful commercial CAD packages, such as hp-EEsof's TouchtoneTM or LibraTM and OSA's Osa90/hopeTM. Advanced high-power asymmetrical iris coupled TE103/TE201 filters with high edge steepness show that the presented hybrid method is also applicable to more specialized design tasks. Its accuracy is verified by measurements and by comparison with the results of the conventional mode-matching/modal scattering matrix technique. © 1997 John Wiley & Sons, Inc.
