Radio electro-magnetic compatibility and application of high-TC superconducting technology

Recent research and development activities on measurement technologies and countermeasures for establishing the electromagnetic compatibility (EMC) of mobile radio equipment with electronic devices and biological safety issues are introduced. EMC studies of medical devices are focused on, and SAR measurement technologies for mobile radios are discussed. Moreover, a cryogenic receiver front end using a high temperature super-conducting filter for mobile base stations is proposed as a promising technology that allows the transmission power of mobile communication systems to be lowered, a desirable result with regard to EMC.
