    A planar asymmetric crossover coupler has a first branch to a seventh branch. The first branch to the fourth branch form a first region having a first port and a fourth port. The fourth branch to the seventh branch form a second region having a second port and a third port. The characteristic impedance of each branch is determined according to the load impedance and power distribution ratio of each port.
