| Abstract: | The coupling device is one of the most important devices for the power line communication systems. A convenient,safe and high efficiency couple device is the basis to realize power line communication of high frequency carrier signal. In this paper,we firstly analyze the requirement of the coupler's structure and frequency band from the view of the network's structure and signal transmission characteristics. And we research the distribution impedance character in high frequency,further more the design principle of coupling device is advised. Finally,the design and realization of two kinds of technology and devices are introduced. |
