Multi-scale tunable filter covering a frequency range of 6.5:1

A multi-scale filter topology is proposed in the form of a switched comb-line structure loaded by varactors. This topology is capable of implementing a tunable frequency response with consistent performance over very large tuning ranges. Two prototype filters of orders two and four have been fabrica...

Zusammenfassung:A multi-scale filter topology is proposed in the form of a switched comb-line structure loaded by varactors. This topology is capable of implementing a tunable frequency response with consistent performance over very large tuning ranges. Two prototype filters of orders two and four have been fabricated in a coplanar geometry. The filters are tunable in a 6.5:1 frequency range.
