Abstract
In this study, a novel ka‐band compact‐size branch‐line coupler was proposed. The coupler was designed and fabricated with WIN Semiconductors 0.15‐μm pseudomorphic high electron‐mobility transistor process. The design method, simulation data, and measurement results of the proposed coupler were also discussed. The coupler occupied less than 45% of the circuit area compared with conventional design at 30 GHz, and did not implement any lumped elements via‐hole grounding, and bonds wire, making it simpler to design, easier to fabricate, and lower cost. © 2007 Wiley Periodicals, Inc.
