    Abstract: Testing devices such as integrated circuits (IC) with integrated antennas configured for millimeter wave (mmW) transmission and/or reception. A DUT may be mounted to an interface in a measurement fixture (e.g., a socket, anechoic chamber, etc.). Power and data connections of the DUT may be tested over the interface, which may also provide connections (e.g., wired) for input/output signals, power, and control and may also provide positioning. Radio frequency (RF) characteristics of the DUT may be tested over-the-air using an array of antennas or probes in the radiating Fresnel zone of the DUT's antennas. Each of the antennas or probes of the array may incorporate a power detector (e.g., a diode) so that the RF radiating pattern may be measured using DC voltage measurements. Measured voltage measurements may be compared to an ideal signature, e.g., voltage measurements expected from an ideal or model DUT.

    Abstract: Various embodiments are presented of a system including an alignment fixture for testing (e.g., rapidly and cheaply) phased array antennas and other devices configured for radio frequency (RF) transmission and/or reception. A device to be tested (e.g., the device under test (DUT)) may be positioned in a testing position by the alignment fixture. The alignment fixture may provide a configurable level of friction to retain the DUT in the testing position. The alignment fixture may provide isolation from electromagnetic interference for the DUT while in the testing position.

    Abstract: Various embodiments are presented of a system and method for testing (e.g., rapidly and cheaply) devices with antennas configured for radio frequency (RF) and/or millimeter wave (mmW) transmission and/or reception. A device to be tested (e.g., the device under test (DUT)) may be mounted to an interface in a measurement fixture (e.g., a socket, anechoic chamber, etc.). Power and data connections of the DUT may be tested over the interface, which may also provide connections for input/output signals, power, and control and may also provide positioning. RF characteristics (e.g., including transmission, reception, and/or beamforming) of the DUT may be tested over-the-air using an array of antennas or probes.
