  • Patent number: 11892492
    Abstract: Embodiments herein relate to a testing apparatus for coupling with a device-under-test (DUT). The apparatus may include a base portion configured to couple to a testing platform, wherein the base portion is configured to rotate the DUT around a first axis. The apparatus may further include an arm portion configured to rotate the DUT around a second axis perpendicular to the first axis. The apparatus may further include a platform portion configured to couple to the DUT. Other embodiments may be described and claimed.
    Type: Grant

  • Patent number: 11275035
    Abstract: Embodiments herein provide a test apparatus and system for a millimeter wave reflection test to measure propagation of millimeter wave signal through a material at various incident angles. In one example, the test apparatus may include a mechanized arch over a base plate, the mechanized arch including antenna carriers coupled to the mechanized arch and configured to hold respective antennas. A motor assembly moves the antenna carriers along the mechanized arch while maintaining the antenna carriers at symmetrical (equal and opposite) angles with respect to the base plate.

  • Patent number: 8229352
    Abstract: A device has an RF mixer, an IF mixer module, a single synthesizer, a frequency divider, a single side band mixer and a frequency quadrupler. The single synthesizer generates a signal to the IF mixer module, the frequency divider, and the single side band mixer. The single side band mixer mixes signals from the single synthesizer and the frequency divider. The frequency quadrupler receives the output of the single side band mixer. The RF mixer is coupled to the frequency quadrupler and the IF mixer module.
