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 .

ABSTRACTThe current fabrication methods used to produce many antennas are limited by variances in the precision and skill levels of individual laborers. These variances slow production and often create inconsistent results. As radio-frequency transmitter and receiver design moves towards higher operating frequencies, the physical dimensions of the supporting antennas decrease. Smaller sizes add new complexities to the fabrication of these antennas. Several designs that may be considered high-performance antennas are difficult to reproduce; many times, they cannot be fabricated at all due to the sophisticated patterning and precision necessary for successful function. Direct-write technologies provide the tools necessary to fabricate unique patterns in two and three dimensions. A demonstration of a directly written antenna, constructed from a silver-based thick-film paste pen-deposited onto cylindrical alumina substrates, is presented for review
