A high frequency probe card includes at least one substrate having at least one first opening, an interposing plate disposed on the at least one substrate and having at least one second opening corresponding to the at least one first opening, a circuit board disposed on the interposing plate and having a third opening corresponding to the at least one first and second openings, and at least one probe module including at least one N-type ground probe and at least one high frequency signal probe passing through the corresponding substrate, the interposing plate and the third opening and being electrically connected with the circuit board. Each high frequency signal probe includes an N-type signal probe and a first conductor corresponding to the N-type signal probe and being electrically connected with the N-type ground probe. An insulation layer is disposed between the first conductor and the N-type signal probe. |
