Equal power divider can be realized in many ways. Simplest is T-junction microstrip power divider. Next three types provide isolation: Wilkinson power divider, provides isolation between two output ports. Hybrid power divider (with one port terminated with 50 Ohms). And also ratrace coupler can be used as power divider (with one port terminated with 50 Ohms).
I have seen only T-junction, Wilkinson and hybrid-coupler power dividers.
Why some designs use hybrid coupler power dividing (phase shift is not required). One part of signal is goes to TX, another part to RX path. Why not using simple Wilkinson?
Anyone used rat-race as a power divider? As am mixer it has wider bandwidth than hybrid couplers, i guess as a power divider it performs better too?
I am sure all those cases could be compared in simulation, but i can't guarantee i can design each one at it's best performance, so comparison would be wrong.
