Abstract

The invention discloses a C-waveband high-power solid-state power amplifier. The power amplifier comprises a drive stage power amplifier, a final stage power amplifier, a monitoring unit and a power supply. The final stage power amplifier comprises a one-to-eight splitter, first to eighth hot plug power amplifiers and an eight-in-one combiner; the splitter and the combiner are mutually isolated with the hot plug power amplifiers respectively through a binary Wilkinson power splitting circuit and a high power waveguide magic T; and the hot plug power amplifiers realize electrified hot plug through controlling power supply and detecting an output power and a reflection power. According to the power amplifier provided by the invention, the electrified hot plug of the final stage power amplifier is realized in adoption of the splitter/combiner with isolated ports and the modularized hot plug power amplifiers; the device maintainability is improved; the system stability is enhanced; and in adoption of eight-way hot plug power amplifiers, the 1KW power output of the continuous waves is realized through parallel power combination.

Description

technical field [0001] The invention relates to a C-band high-power solid-state power amplifier in the communication field, and is particularly suitable for a transmission device for completing radio frequency signal power amplification in a transmission channel of a C-band communication system. Background technique [0002] With the development of scattering communication technology, the requirements for the transmission power of the C-band communication system are increasing. At present, the solid-state power amplifiers widely used in the C-band of the scattering communication system are mostly in the order of hundreds of watts, and each power amplifier module is fixed on the heat sink by screws. The reduction of maintenance and reliability cannot meet the requirements of high reliability and rapid maintenance of scattered communication. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a C-band all-solid-state power am...
