Expert system for microwave filter design

An expert system for microwave filter design, FIRE (FIlteR dEsigner), has been developed for the straightforward optimum design of edge-coupled microstripline bandpass filters. The system incorporates the design expertise and knowledge of experienced microwave-circuit design engineers as a knowledge database, necessary design data as a microwave database, and commercially available microwave circuit simulators. It can also generate MIC pattern layout data on magnetic tape. Thus, the system makes it possible even for inexperienced engineers to design bandpass filters with experienced engineers´ design quality in a much shorter time than conventional design procedures.<>
