broadband branchline coupler

I designed branch line coupler for 1.6GHz.
My desired frequency is 800-2500MHz.
I want to design 3dB response for entire band width.
How to design the broad band coupler for required band width.

You can use more stages to get wider bandwidth.

very tough task, you can get success if lose coupling

In AWR, there is some examples:
Stripline_Coupler: 1.8~2.8GHz
Hybrid_Coupler
You can try to modify these files to get your target.
Good luck.

I said tough as the freq BW is more than 1.5 octaves by the goal.
The example is less than octave.
I suggest design of Power divider than hybrid coupler for this application.
