Residential Electricity

With the development of the smart grid, residential electricity services have a higher bandwidth and frequency requirement to the power system communication , the existing power 230MHz narrow-band data transmission communication has been unable to meet the needs of the two-way interaction between the users and the smart grid. In terms of current communication technology in the power system, this paper introduces a wireless broadband radio frequency chip ,which supports 100MHz to 1.2GHz frequency range, and 5KHz to 2MHz tunable bandwidth.With the chip embedded in intelligent electricity interactive terminals, distribution monitoring terminals and other devices, it can achieve flexible and intelligent electricity services. This paper describes the architecture of the RF chip,and gives key technology solutions such as broadband matching, adjustable IF bandwidth of the channel, sums up the advantages of the chip,presents the application in the smart grid. The analysis finds that the chip has a variety of charateristics such as high integration, good redundancy, versatility, flexibility and so on, and can satisfy the growing application needs of power speacial network,and has an extremely promising market .
