The radio frequency (RF) probe socket is disclosed. The probe socket includes a conductive noise shielding body configured to accommodate the plurality of signal probes to be parallel with one another while exposing opposite ends thereof, and shield noise; upper and lower noise shielding walls configured to be extended from the noise shielding body to some areas between the exposed opposite ends of the plurality of signal probes; and upper and lower holding members configured to be arranged on top and bottom sides of the noise shielding body, support the exposed opposite ends of the plurality of signal probes, and comprise accommodating grooves accommodate the noise shielding walls, respectively. With this, the noise shielding wall extended from the shielding block makes a shield between the signal probe pins passing through the upper and lower holding member, thereby preventing crosstalk between the signal probe pins.
