Abstract: A radio frequency (RF) testing apparatus, for testing device under test (DUT) comprising a receiving antenna, includes a pair of transmitting antennas transmitting wireless communication signals to the receiving antenna, a shielding box, a first filter and a second filter. The shielding box includes a transmitting box, a receiving box for receiving the DUT, a connecting box connecting between the transmitting box and the receiving box and a pair of transmitting antennas fixed on the transmitting box and suspending towards the connecting box. The connecting box includes a microwave absorption medium on the connecting box and communicates with the receiving box. The first filter is mounted on the connecting box and the transmitting box to electrically connect with the transmitting antenna. The second filter is mounted on the receiving box to electrically connect with the DUT.

Abstract: A card socket assembly includes a base, two latching mechanisms, and an elastic member. The base includes a mounting surface. The two latching mechanisms are oppositely fastened to the mounting surface. The two latching mechanisms and the mounting surface cooperatively enclose a card slot, used to receive a data card therein. The elastic member is disposed adjacent to the card slot and exposed within the card slot. The elastic member elastically biases the data card against the latching mechanisms.
