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: Marchand balun
Unread postPosted: Thu May 13, 2004 4:38 am
I wonder how well balanced and unbalanced ports in Marchand balun can be matched simultaneously? What I simulated is that either unbalanced ports or balanced port can have good matching but simultaneously about VSWR=2 was achieved. Is there something wrong in my circuit? Unbalanced port is 50 Ohm and balanced ports are 25 Ohm each or 50 Ohm differentially.
