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.
 

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.

Regards,
