Tandem coupler reference

3 months 3 weeks ago #714 by Microwaves101
I am looking for the original reference on tandem 3dB couplers.

I have seen this paper referenced, but can't find a copy of it:

Shelton, J. P., J. Wolfe, and R. Von Wagoner, ‘‘Tandem, Couplers and Phase Shifters for Multi-Octave Bandwidth,’’ Microwaves, Vol. 4, April 1965

If anyone has this (or better reference please get in touch.

Are you interested in a 90 degree hybrid or a 180 degree hybrid?
