Abstract
Abstract A high-frequency power synthesizing apparatus having a plurality of distributors arranged in a plurality of stages, a plurality of amplifiers which are supplied with outputs from a final stage of said power distributors and which amplify these outputs to a predetermined level, and a power synthesizing unit including initial-stage power synthesizers supplied with outputs from said amplifiers and a final-stage synthesizer which outputs power to an external load. The final-stage power distributors and the initial stage synthesizers are constituted by 0°-hybrid modules. The output level of each amplifier is regulated and made constant by being compared with a predetermined level. The output levels of the amplifiers can be displayed on an external display.
