摘　　要：针对微波通信技术的特点,设计了一种采用数字基带拉远技术的微波通信设备,该设备是3G、4G网络微基站技术在特定应用场景的进化。在设备基础上论述了LTPo E++标准和传统Po E标准的差异,提出并实现了一种基于LTPo E++标准的拉远供电方案。设计采用Linear公司的以太网受电设备(PD)控制器LT4275A和以太网供电设备(PSE)控制器LTC4266,共同组成稳定可靠的供电电路,以满足微波通信设备的拉远供电要求。实际工程应用表明:该设计简单高效,可满足不大于90 W的微波设备室外单元(类似微基站)的供电要求,提高了微波设备供电系统的可靠性和经济性,具有较高的推广价值。According to the characteristics of microwave communication technology, the design of a microwave communication device with digital baseband, the device is a 3G, 4G micro base station network technology in the specific application scenario evolution. The devices based on the LTPoE＋＋ standard and discusses the difference between the traditional PoE standard, proposes and implements a remote power supply scheme based on LTPoE ＋＋ standard drawing. The design uses Linear＇s Ethernet power device （PD） controller LT4275A and Ethernet controller LTC4266 power supply equipment （PSE）, composed of power supply circuit is stable and reliable, in order to meet the needs of microwave communication equipment remote power supply requirements. Application results show that the design is simple and efficient, which can meet the microwave equipment outdoor unit is not more than 90 W （similar to the micro base station power supply requirements） to improve the reliability and economy of power supply system of microwave equipment, has higher application value.
