Challenges facing microwave filter engineers - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

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.

Thanks

James

I'd add:

1. Passband VSWR control/Passband ripple

2. Repeatability in manufacturing

3. Simplified tuning in manufacturing

4. Phase linearity

5. Spurious responses
