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? Top yendori Post subject: Re: help to design

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. https://michaelgellis.tripod.com/direct.html
