| asymmetric filters - 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. ofourquin Post subject: asymmetric filters Posted: Thu Sep 04, 2008 7:27 am Lieutenant Joined: Thu Sep 04, 2008 7:25 am Posts: 3 hello i would like to know how to design asymmetric filters. thinks Top nubbage Post subject: Posted: Fri Sep 05, 2008 4:12 am General Joined: Fri Feb 17, 2006 12:07 pm Posts: 218 Location: London UK Hi ofourquin In what sense are they to be asymmetrical? Impedance unequal at input and output? Or unequal roll-off slope LF side vs HF side? Bandpass, low-pass, or high-pass, or any? There are some good websites that include java script routines for interactive filter designs.

It is also call coupled filter in “Handbook of Filter Synthesis” books from Zverev. The impedance is set to 50 Ohm in input and output for UWB applications [3.1 ; 10.6] GHz. Top ofourquin Post subject: Posted: Mon Sep 08, 2008 11:15 am Lieutenant Joined: Thu Sep 04, 2008 7:25 am Posts: 3 Just a precision it is not bandpass filter based on the LP filter theory where where we find capacitor with a inductance in series ps sorry for my bad english Posted 11/12/2012 | ||||||
