Advice for Power divider/combiner

Me and my senior student friends trying to design an 800w power divider and combiner at 3Ghz. We use microstripline, silver as conductor and Rogers 6010 as substrate.
Which type of divider/combiner types is suitable for our application? So far we worked on Wilkinson and Gysel dividers.

This is an old design which is not suitable for our project. But we are curious about which type of divider used can you identify it?
Also, do you know any good calculator in order to calculate minimum width for the conductor?

Any kind of help/tip appreciated.

they are "branch line couplers". work fine, but only over a narrow bandwidth. The bigger one is a "two section" coupler and has a bigger bandwidth
