| filter design problem - RF Cafe Forums | ||||||
|
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
Facebook page, please do.
Below are all of the forum threads, including all the responses to the original posts. YZ Post subject: filter design Posted: Tue Aug 23, 2005 8:12 am hello all, I designed a BPF filter at 7GHz BW=400MHz. the filter topology is chebychef and the type of microstrip edge coupled. I use the Ansoft Designer software. my problem is bad VSWR,after EM simulation i got -6dB R.L. what could be the reason for this ? how can i improve the R.L. ? thanks Top Guest Post subject: Posted: Tue Aug 23, 2005 9:31 am What is the ripple you designed for. The amount of ripple will dictate the VSWR. Top YZ Post subject: Posted: Tue Aug 23, 2005 4:00 pm Anonymous wrote: What is the ripple you designed for. The amount of ripple will dictate the VSWR. The ripple i designed for, is 0.01dB. Posted 11/12/2012 | ||||||
