Abstract
A method of designing a microwave filter using a computerized filter optimizer, comprises generating a filter circuit design in process (DIP) comprising a plurality of circuit elements having a plurality of resonant elements and one or more non-resonant elements, optimizing the DIP by inputting the DIP into the computerized filter optimizer, determining that one of the plurality of circuit elements in the DIP is insignificant, removing the one insignificant circuit element from the DIP, deriving a final filter circuit design from the DIP, and manufacturing the microwave filter based on the final filter circuit design.

A method, comprising:
- receiving, by a processor of a computing system, a first filter circuit model comprising a plurality of circuit elements, wherein the plurality of circuit elements comprises a plurality of resonant elements and one or more non-resonant elements;
- selectively removing one or more circuit elements of the plurality of circuit elements responsive to a comparison of a characteristic of each of the one or more circuit elements to a threshold value;
- and
- generating, by the processor, a second filter circuit model comprising a subset of the plurality of circuit elements that were not removed.
A system, comprising:
- a processor executing an element removal design engine and a memory storing a first filter circuit model comprising a plurality of circuit elements, wherein the plurality of circuit elements comprises a plurality of resonant elements and one or more non-resonant elements;
- and wherein the element removal design engine is configured to:
- selectively remove one or more circuit elements of the plurality of circuit elements responsive to a comparison of a characteristic of each of the one or more circuit elements to a threshold value;
- and
- generate a second filter circuit model comprising a subset of the plurality of circuit elements that were not removed.
