I would really appreciate some insight from the members of this group on the major challenges to be overcome by microwave filter engineers in the future. To some extend I realise that this depends on the intended application. Some of forces presently driving development include: 1) miniaturisation, 2) simplification of design rules, manufacture and circuit layout, 3) improved rate of cut-off and 4) reduced insertion loss. Can anyone add to this list or provide information about the challenges which apply in certain specific applications.

I'd add:
1. Passband VSWR control/Passband ripple
2. Repeatability in manufacturing
3. Simplified tuning in manufacturing
4. Phase linearity
5. Spurious responses

Kirt Blattenberger,

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
