help to design a 1:6 transformer - 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.

I want to design a high power(200w CW) directional coupler as following circuit,It work over the range from (30~80)MHz.
I am going to use a 3:5 voltage ratio transmission-line transformer as a 1:3 impedance ratio transformer.
However I don't know how to design 1:6 impedance ratio transformer,who can help me?

That's an interesting approach, but as an engineer I would suggest simple and practical.
There is lots of reference on how to design core and wire directional couplers.
