Introduced: January 2011

Title

Titles differ between systems:

IPC: by variation of conductive properties, e.g. by variation of dimensions

CPC: by variation of conductive properties, e.g. by dimension variations

Full titles differ between systems:

IPC:

CPC:

Details of coupling devices of the kinds covered by groups H01R12/70 or H01R24/00 - H01R33/00 > specially adapted for high-frequency, e.g. structures providing an impedance match or phase match (non-coaxed protective earth or shield arrangements H01R13/648; coaxed connectors specially adapted for high frequency H01R24/40) > Impedance matching > by variation of conductive properties, e.g. by dimension variations

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 2011.
