An integrated radio frequency system based on satellite communication and scatter communication

Abstract

This application provides an integrated radio frequency (RF) system based on satellite communication and scatter communication, including an RF unit link and a power supply system. The RF unit link is located between a scatter modem, a satellite communication modem, and a feed network, and includes a Ku-band up-conversion power amplifier, a scatter low-noise amplifier, a satellite communication low-noise amplifier, a Ku-band down-converter, a Ka-band down-conversion low-noise amplifier, and a Ka-band up-conversion power amplifier. The power supply system includes a UPS power supply unit and an ODU power supply unit. The UPS power supply unit receives an external input source and outputs power voltage to each module of the RF unit link through the ODU power supply unit. This application can integrate satellite communication and scatter communication, improving integration, reducing size, and saving costs. Furthermore, it allows for flexible switching between satellite communication and scatter communication based on actual field communication conditions, adapting to more communication application scenarios and improving communication performance.
