ISO/IEC 10373-7:2008 ISO/IEC TR 18047-3 1. Schematic The layout of the impedance matching network was designed to hold either the components for the basic bit-rate fc/128 version of ISO/IEC 10373-6:2001 as well as ISO/IEC 10373-7, ISO/IEC TR 18047-3 and ECMA-356 or for the high bit-rates (fc/64, fc/32 and fc/16) version of ISO/IEC 10373-6:2001/FDAM 5:2007. Following draft rev. 2 of ISO/IEC 10373-6, the resistor Rext is wired on the ground side of the antenna coil. Note: Fitting for ISO/IEC 10373-7, ISO/IEC TR 18047-3 and ECMA-356 is the same as for fc/128.
