A tapered microstrip power combiner is proposed (Singapore Patent (9610362‐7) pending) whose in‐phase input ports are located on a straight line rather than located on an arc, making it highly suitable for high‐power SSPAs. To achieve equal in‐phase transmissions between the input ports and the output port, holes are arranged in the middle of the structure. Experimental results of a ten‐way combiner operating at 10 GHz confirm the viability of this approach. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 15: 339–342, 1997.
