一种卫星移动通信终端一线通射频接口设计

Design of a 1-wire RF Interface for Satellite Mobile Communication Terminals

文章设计了一种卫星移动通信终端的一线通射频接口方案,支持低功耗联动控制设计。本方案是在一线通射频接口中增加控制单元,结合基于卫星移动通信终端基带处理单元的工作状态共同完成。通过动态调整射频前端和外围组件,来带动整机联动控制,实现降低功耗。该设计帮助终端在待机和工作状态下,可以将射频和主机的功耗关联,提高续航能力。在卫星信道使用情况下,为低功耗小型化卫星终端开发提供帮助。

The article designs a one line RF interface scheme for satellite mobile communication terminals,which supports low-power linkage control design.This plan is to add a control unit to the first line communication RF interface,combined with the working status of the baseband processing unit based on satellite mobile communication terminals.By dynamically adjusting the RF front-end and peripheral components,the entire machine is driven to achieve linkage control and reduce power consumption.This design helps terminals associate the power consumption of RF and the host in standby and working states,improving their battery life.Provide assistance for the development of low-power miniaturized satellite terminals in the use of satellite channels.
