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. fxhfzy Post subject: coaxial line transformer Posted: Sat Jul 04, 2009 3:27 am Captain Joined: Fri Jun 26, 2009 6:22 am Posts: 13 I am designing a 200W, IMD3< -40dBc amplifier for 30-90MHz application, I am going to using freescale's MRF6VP2600HR6.The following is test circuit: I want to ask three quentions: 1.There are two baluns(T1 and T2) , they are coaxial line transformers, is there anyone known the parameters of these baluns(length and Zo)? (Baluns are made by Comm Concept, and I have email Comm Concept company, but they didn’t reply me) 2.Since the Comm Concept company didn’t reply me, is there any other products I can use to substituted for T1 and T2? 3.Maybe I have to make it myself, can you give me some reference on how to make a balun like these?

Siliconix also had App Notes once in a while that were a great help in understanding how to design input/output matching sections for bipolars and FETs. _________________ At bottom, life is all about Sucking in and blowing out.
