Abstract
A probe card which is capable of transmitting high-frequency signals provided by a DUT, and the DUT includes an output pin group and an input pin group for sending and receiving the high-frequency signals respectively. The probe card includes a first signal pin group, a second signal pin group, and a band circuit. The first signal pin group is made of a conductive material, and is used to contact the output pin group; the second signal pin group is made of a conductive material too, and is used to contact the input pin group; the band circuit is electrically connected to the first signal pin group and the second signal pin group to allow signals within a first bandwidth and a second bandwidth to pass therethrough.
