Heterogeneous base plate high frequency interconnect structure

The utility model discloses a heterogeneous base plate high frequency interconnect structure belongs to the radiofrequency signal transmission, technical field. It includes still to be located the radio frequency connection structure between first base plate and the second base plate that radio frequency connection structure includes miniature elastic sleeve and fine elastic metal post, has the cavity structure on the second base plate including mutual heterogeneous first base plate and second base plate, the cavity structure includes outside cast cavity and inside flute profile cavity, duringminiature elastic sleeve and fine elastic metal post imbedded outside cast cavity and inside flute profile cavity respectively, first base plate was closely pressed with the second base plate and isjoined in marriage, and miniature elastic sleeve and the deformation of fine elastic metal post pressure -bearing form the radio frequency coaxial configuration. The utility model discloses low -lossbetween heterogeneous base
