ka band high power amplifier

Abstract

The invention discloses a KA frequency band high-power amplifier and its realization method, comprising: a frequency conversion unit, a power amplifier unit, a power supply unit, and a monitoring unit; wherein, the frequency conversion unit is connected with a crystal oscillator generating a 10MHz reference signal through a first filter; The monitoring unit is provided with a 10 / 100M Ethernet interface for communication connection with external equipment. The present invention provides a KA frequency band high-power amplifier and its implementation method, which can convert the frequency of the intermediate frequency signal by setting a frequency conversion unit, so that it can adapt to the signal communication of the KA frequency (wave) band, and at the same time, add Ethernet communication to the amplifier Interface, so that the amplifier can directly communicate with the outside, which is convenient for monitoring and parameter adjustment of its working status. Further, by setting a reference signal source on the amplifier, it can work independently without the intervention of external equipment. The adaptability is better, and the stability and controllability of the equipment work are stronger.

Description

technical field [0001] The invention relates to a device for use in communication situations. More specifically, the present invention relates to a KA band high power amplifier used in satellite communication and its implementation method. Background technique [0002] With the continuous development of satellite technology in my country, the demand for satellite broadband big data is becoming more and more urgent. At present, most domestic commercial satellites use C-band or KU-band, which can no longer meet the growing demand for communication services, and the space resources of C-band or KU-band It is also becoming rarer and rarer. KA-band satellite communication has the advantages of wide operating frequency, narrow beam, large communication capacity, and small terminal size, which has become the current development trend of satellite communication. [0003] The KA-band solid-state power amplifier is a key module in the satellite earth station launch system. Its functio...

AI Technical Summary

Problems solved by technology

[0004] The existing KA satellite power amplifiers on the market are mainly for local monitoring and control. If the power amplifier needs remote monitoring or parameter adjustment during actual use, it can only be viewed and controlled on site. If the power amplifier is used in an unattended ground station, the ground station satellite power amplifier If the parameters need to be adjusted, people need to be sent to the field to operate; in addition, the satellite communication amplifiers in the prior art usually need to use an additional device to give the corresponding reference signal. If there is no reference signal, the amplifier cannot be in the working state.
