1. contact device that is used for high frequency measurement;

  • Have and be used for the contact jaw (12) that electrically contacts with planar structure;

    Wherein locate to be provided with and have at least two coplanar conductors structures by the conductor (14) of dielectric (10) supporting at contact jaw (12);

    Wherein between dielectric (10) and contact jaw (12) the structure probe so that space free ground and the conductor (14) of coplanar conductors structure flexibly is set for maintenance dielectric (10) it is characterized in thatAt least one device that is used for transmission of electric signals (24) is set on dielectric (10);

    The said device (24) that is used for transmission of electric signals is electrically connected with at least one conductor (14) of coplane conductor structure so that this is used for the signal of device (24) transmission of transmission of electric signals from least one conductor (14) that is electrically connected with the said device (24) that is used for transmission of electric signals;

    Wherein between per two conductors (14) of coplanar conductors structure;

    On the whole length of coplanar conductors structure, construct each slit so that on the length of coplanar conductors structure, produce constant characteristic impedance;

    Said contact device comprises the coaxial cable end (16) with coaxial conductor structure, the wherein said device (24) that is used for transmission of electric signals link to each other with at least one coaxial cable joint (18) of coaxial conductor structure so that the said device (24) that is used for transmission of electric signals at least one conductor (14) that is electrically connected with the said device (24) that is used for transmission of electric signals and coaxial conductor structure at least one with coaxial cable joint (18) that the said device (24) that is used for transmission of electric signals is electrically connected between transmission signals;

    AndSaid dielectric (10) extends up to coaxial cable end (16).
