| 摘 要： | 介绍了一种在同轴电缆上,射频和基带信号复用传输的新方法。设计了射频信号和基带信号隔离电路,采用C-MBUS标准传输基带信号,在长为1 km、传输射频信号功率为40 d Bm的同轴电缆上,达到了4 800 b/s的数据传送速率,且同时可以为通信从机节点提供10 m A的电流。该方法具有硬件电路简单、成本低廉,容易组网的优点,适用于在射频线路上同时传输低数据速率的附加信息。

| Abstract: | A new method to transmit both baseband signal and RF（radio frequency）signal in a coaxial cable is introduced. A circuit to isolate baseband signal and RF signal was designed. The baseband signal is transmitted according to CMBUS Standard. On the 1 km coaxial cable,which transmits 40 dBm RF signal,4800 bps transmission rate was achieved,and 10 mA current can be provided for slave node. It has the advantages of simple circuit,low cost and easy networking. It is applied to transmitting the additional information of low data rate in the RF coaxial cable. |
