MCM Microwave Filter Research

MCM has high density integration, multilayer wiring, the advantages of high frequency performance. MCM is the important means to the miniaturization of electronic systems. MCM is widely used in radar, communication, electronic warfare, equipment and other military/civilian areas. Developed countries put a high value on MCM because MCM has a lot of advantages, for example MCM raises density and shortens interconnection space. MCM is a mainstream in the field of electromagnetic field and microwave technology and frontier, and of great value in theoretical research and engineering application.Aiming at the big size of microstrip filter, this thesis adopts the filter design method that is based on coupling matrix. The thesis calculates coupling matrix. Then combining with the electromagnetic simulation software HFSS, the thesis designs six kinds of MCM filter structure, and analyzes the general rule of filter optimization. In this thesis, the designed filter materials is RO4350B and the process is MCM - L. The size of MCM filter decreases. The S11 of four cavities filter is less than-10 dB。 The S11 of hairline filter is less than - 15 dB。 The S11 of open-end filter is less than -20dB。 The S11 of four cavities open loop filter is less than -15dB。...
