HIGH-OUTPUT POWER AMPLIFIER USING COAXIAL WAVEGUIDE SPATIAL COUPLER

摘要

The present invention relates to a high-output power amplifier and, more specifically, to a high-output power amplifier using a coaxial waveguide spatial coupler. According to the present invention, the high-output power amplifier comprises: a spatial power distributor which radiates input signals into a provided distributor coaxial waveguide and which distributes and outputs, as n number of distribution signals, input signals radiated through n number of distributor taper pin-lines provided inside the distributor coaxial waveguide; n number of amplifiers for outputting n number of amplified distribution signals by amplifying each of the inputted distribution signals; and a spatial power coupler which radiates each of the inputted amplified distribution signals into a coupler coaxial waveguide through n number of coupler taper pin-lines provided inside the coupler coaxial waveguide, and which combines and outputs the radiated amplified distribution signals as one signal through a provided pin. According to the present invention, a high-output power amplifier using a coaxial waveguide spatial coupler, which can be applied to a high-output system, can be provided.
