This paper presents the design of a broadband branch-line coupler. The proposed coupler features compact size on a single circuit layer structure. For the high power capability, broadband property and cost effectiveness, we have designed, fabricated and tested a new three-branch hybrid with lumped-distributed-elements. It has the fractional bandwidth of 45% at the center frequency of 2 GHz. Also, it shows the size reduction more than 35 % compared with the conventional design method. © 2005 IEEE.
