Abstract
Power-combining devices, and more particularly spatial power-combining devices with increased output power are disclosed. Increased output power may be realized by increasing a number of transmission paths for amplification that are associated with each amplifier assembly of a spatial power-combining device. Each transmission path may include an input antenna structure, an amplifier, and an output antenna structure for providing amplification of signals that pass therethrough. In this manner, a total number of transmission paths for amplification may be increased without having to increase a total number of amplifier assemblies. Further improvements to electrical separation and stability between neighboring amplifier assemblies may be provided by electrically grounded conductive sheets that are arranged between neighboring amplifier assemblies.
