An addition:
?
As you can see from the phase plot the deviation from 90 deg is less than 5 deg for the range: 2.4 - 37 MHz. The design can be easily scaled to another frequency range.
?
But note: there is no constant phase difference between the input and outputs. Only the two outputs maintain an approximately constant phase shift between them.
