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.

I designed a BPF
filter at 7GHz BW=400MHz.
the filter topology is chebychef and the type of microstrip edge coupled.
the Ansoft Designer software.
my problem is bad VSWR,after EM simulation i got -6dB R.L.
be the reason for this ?
how can i improve the R.L. ?

What is the ripple you designed for. The amount of ripple will
dictate the VSWR.
