笙科电子(AMICCOM)于2011年7月发表新一代应用于智能电网的射频芯片，该芯片料号为A7108，支持中国智能电网所选用的470MHz ~ 510MHz，以及欧洲无线自动读表所使用的868.3MHz 与868.95MHz频段，除此之外，A7108当然也支持1GHz 以下免执照的ISM Band应用 (300MHz ~ 950MHz)，比如日本的310MHz，欧美及亚洲常见的433.92MHz，美国与台湾的允许的915MHz等频段。(Sheng Ke Electronics (AMICCOM) published a new generation of radio frequency chips used in smart grid in July 2011. The chip is A7108, 470MHz ~ 510MHz for Chinese smart grid, and the 868.3MHz and 868.95MHz band used in European wireless automatic reading meter. In addition, A7108 also supports no license under 1GHz. ISM Band applications (300MHz ~ 950MHz), such as 310MHz in Japan, 433.92MHz in Europe and America and Asia, the permitted 915MHz in the US and Taiwan.)
