Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Challenges facing microwave filter engineers Posted: Thu Jan 05, 2006 9:04 am
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.

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