Abstract
A testing system and method for testing integrated circuits with radio frequency (RF) antennas is disclosed. The system includes an alignment plate for receiving a device under test (DUT) having an RF transmitting antenna, an enclosure surrounding but separated from the transmitting antenna, a receiving antenna in a telescopic enclosure, and a conversion circuit connected to the receiving antenna. The conversion circuit is configured to convert an RF output from the DUT to a direct current (DC) voltage. The DC voltage is used as a proxy for the RF output to test the DUT. When testing chips with RF ports, the chip or ports are surrounded by the enclosure which is non-radio reflective and includes antennas for receiving RF outputs disbursed around the enclosure, or a single antenna. If multiple receiving antennas are used, sequential testing can also detect directional transmission patterns to confirm that the direction is correctly calibrated.
