Quadfilar power divider alternative

[sph2020]

Hi there,

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.

Cheers,
sph

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.

Not quite 1.5 GHz, but this one is designed for GPS L1 (1.575 GHz):
