Abstract

The invention discloses a power amplifying device, comprising: a solid state amplifier used for carrying out power amplification and gain compensation on a downlink satellite signal with a frequency range of 12.25-12.75GHz from a satellite to output a driving signal; a downward Ku frequency band traveling wave tube connected with the solid state amplifier and used for carrying out power amplification on the driving signal after receiving the driving signal to output a satellite downlink signal with an adjustable output power size range, wherein the output power size range is larger than 0 watt and is smaller than or equal to 750 watts. The power amplifying device is used for solving the technical problem that an electronic device in the prior art lacks a high-power traveling wave tube whose working efficiency is a downward Ku frequency band, and achieving a technical effect of obtaining a Ku frequency band high-power traveling wave tube power amplifier.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power amplification device. Background technique [0002] With the continuous development of science and technology, satellite communication technology is becoming more and more mature. Satellite communication has brought great convenience to people's life because of its long communication distance and high communication quality. The satellite communication system is mainly composed of four parts: the space subsystem, the tracking telemetry and command subsystem, the monitoring and management subsystem, and the communication earth station. The communication earth station is a microwave radio receiving and sending station through which users access satellite lines and perform Communication, and an important part of the communication earth station is the power amplifier. [0003] Solid-state amplifiers and microwave tubes are the two main categories of power amplifiers. Soli...
