I am searching for a 4 way power divider/coupler with quadrifilar output (0°,90°,180°,270° phase offsets) operating at 1.5 GHz.
The only thing I found is the SCQA-4-162+ from Microcircuits. Does anybody know any alternatives?
This is the only chip with that specific function I was able to find operating at this frequency.
Perhaps an all-pass filter. Same as or similar to phase-sequence network per this schematic in the Circuits menu of Falstad's animated simulator. Four outputs offset by 90 degree phase shifts.
