HIGH-POWER POWER AMPLIFIER USING COAXIAL WAVEGUIDE SPATIAL COMBINER

摘要

The present invention relates to a high-power power amplifier, and more specifically, to a high-power power amplifier using a coaxial waveguide spatial combiner. According to the present invention, the high-power power amplifier comprises: a spatial power distributor radiating an input signal to the inside of a distributor coaxial waveguide provided therein, and dividing, into n distributing signals, the input signal radiated through n distributor taper pin-lines provided inside the distributor coaxial waveguide, and outputting the n distributing signals; n amplifiers amplifying the input respective distributing signals, and outputting the n amplified distributing signals; and a spatial power combiner radiating the input amplified distributing signals respectively to the inside of a combiner coaxial waveguide through n combiner taper pin-lines provided inside the combiner coaxial waveguide, combining the radiated amplified distributing signals as one signal through pins provided therein, and outputting the one signal. According to the present invention, the high-power power amplifier using a coaxial waveguide spatial combiner applicable to a high-power system can be provided.;COPYRIGHT KIPO 2018
