发明名称 FILTER AND METHOD AND APPARATUS FOR MANUFACTURING FILTERS
摘要 A method of producing filters using lower unloaded Q factor components than filters with the same performance characteristics but requiring higher unloaded Q factor components. The method comprises the step s of defining a desired filter characteristic and applying an algorithm which provides a filter having infinite Q factor elements and having a theoretical characteristic corresponding to the desired characteristic transformed to compensate for the difference between finite Q factor and infinite Q factor elements.
