摘　　要：依据宽带耦合装置的设计要求,采用电容耦合技术设计出满足高速宽带载波通信要求的耦合电路,并对已有的载波收发电路进行改进。通过计算采用五阶切比雪夫Ⅰ型带通滤波电路对接收端的信号进行滤波,以便更准确地接收有用信号,利用Mutisim12对以上电路的滤波性能和耦合性能进行仿真分析。最后对设计出的耦合装置进行测试。结果表明,该电容耦合装置能满足高速宽带载波通信的要求。The coupling device is crucial for high efficient and reliable utilization of broadband power line carrier communication. Based on the design requirements of broadband coupling device,a coupled circuit is designed based on the capacitive coupling technology to satisfy the requirement for high speed broadband carrier communication. Also the existing carrier transceiver circuits are improved,the fifth order Chebyshev type I band-pass filter circuit is used to filter the signal at the receiving end so that desired signals can be received accurately. The filtering and coupling performances of the designed circuit are simulated and analyzed by Mutisim 12. Finally,the physical device of the designed circuit is tested,the result shows that the capacitive coupling device meets the requirements of high-speed broadband carrier communication.
