Description

technical field [0001] The invention relates to a power amplifier component, in particular to a Ka-band linearized power amplifier component. Background technique [0002] Usually, in order to improve the working efficiency and output power of the power amplifier, the power amplifier is often made to work in a saturated state. When the power amplifier works in a saturated state, the efficiency is the best, and the output power is also the largest, but the nonlinear distortion increases sharply, which seriously affects the working performance of the power amplifier. The existing power amplifier components are generally composed of a driver amplifier and a power amplifier, without linearization design, and the nonlinear distortion is serious when the output is saturated. Contents of the invention [0003] The purpose of the present invention is to provide a Ka-band linearized power amplifier assembly, which solves the problem of serious nonlinear distortion when the existin...
