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?

Hi,
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.
