Novel Factor of Merit for Centre-Frequency Tunable Bandpass Filters Comparison
Résumé
This article presents an improved factor of merit for the comparison of center‐frequency tunable bandpass filters. This study draws up a comparison between existing tunable filters for which different commonly used parameters demonstrating their performance are given. A first factor of merit that takes all the major characteristics of such tunable filters into account is introduced. A second factor of merit is proposed to evaluate the filter compactness. These new factors of merit are applied for the comparison of more than 30 recently published papers.
