Re: HYBRID QUADRATURE JH-6-4 or equivalent


 

A few years ago, a similar topic appeared in another group: /g/SimSmith/topic/69302617?.
?
Last year, Chris Smith NX0E shared his hybrid coupler design with me. He based his design on Bedrosian's article "Normalized Design of 90¡ã Phase-Difference Networks" .
?
I have included two of Chris's articles from 1988 in the NX0E_hybrid coupler folder /g/loopantennas/files/NX0E_hybrid_coupler .
I have transferred Chris' idea to LTspice. You can find the LTspice file and the phase difference plot in that folder.

Kind regards
