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.

Hi filter designers!
For narrow single or multiple bandpass
filters it is advantageous using cross-coupled filter designs. Since
cross-couplings cause total absorbability for desired frequencies, a
cross-coupled cavity filter needs fewer resonators than a simple-coupled
one, what will result in a better through loss.
the time and effort to reach optimal solution for cross-coupled filters.
