This letter introduces a new 90 branch-line coupler with

reconfigurable output power ratios (90 BC-ROPR). Unlike a conventional

branch-line coupler structure, each arm of the proposed 90 BCROPR

is defined by an asymmetrically coupled-line, and its characteristic

impedance depends on the configuration of the coupled-line. The

main problem that challenged this structure was unwanted loop resonance

from the inner transmission lines which form a loop in a disconnected

configuration. The proposed structure was designed to obtain 1:1

and 4:1 output power ratios at 3 GHz. Both the simulation and measurement

results confirm that the proposed branch-line coupler successfully

dealt with the loop resonance and achieved excellent performance.
