A radial power-combiner design is presented using broadband probes and a radial cavity configuration. The 8:1 combiner (which can also be used as a power divider) is demonstrated experimentally in both single-ended and differential configurations. The broadband probe is composed of cylindrical conductors and dielectric spacers, arranged on a rod for mechanical stability. The proposed radial power combiner provides low loss, broad bandwidth (8001800 MHz), and high power capability.
