Advanced Synthesis Techniques for Microwave Filters
FEST3D is a software tool capable of analysing complex passive microwave components based on waveguide technology (including multiplexers, couplers and filters) in very short computational times with high accuracy. This suite offers all the capabilities needed for the design of passive components such as optimization and tolerance analysis. Moreover, FEST3D advanced synthesis tools allow designing bandpass, dual-mode and lowpass filters from user specifications.
Advanced coupling matrix synthesis techniques for microwave filter
With the advent of the ‘digital revolution’ that has made possible services such as the world wide web, satellite broadcasting and mobile and trunk telephony, the finite RF spectrum allocated for terrestrial and satellite telecommunication systems is becoming increasingly crowded. This has impacted significantly upon the performance required from the microwave equipment that comprises these systems. In the case of microwave filters, greater in-band linearity to avoid signal distortion and out-of-band isolation to suppress interference are routinely specified, which can only be satisfied by advanced filtering characteristics. This article presents the coupling matrix approach to the synthesis of prototype filter networks, enabling the realization of the hardware embodying the enhanced performance needed by today’s high capacity systems.
