Abstract: Methods and systems for automated testing of extremely-high frequency devices are disclosed. A device under test (DUT) is set in a simultaneous transmit and receive mode. The DUT receives a lower frequency radio frequency (RF) signal from a test unit and up-converts the lower frequency RF signal to a higher frequency RF signal. The DUT transmits the higher frequency RF signal using a first antenna, and receives the higher frequency RF signal using a second antenna. The DUT down-converts the received higher frequency RF signal to a received test RF signal and provides the received test RF signal to the test unit for comparing measurements derived from the received test signal to a design specification for the DUT.

Abstract: Devices and methods for detection of active return loss for an antenna element of a plurality of antenna elements of a phased array antenna are provided. An exemplary device can convert a voltage differential at an input of a power amplifier (PA) to first current. The device can convert a coupled voltage corresponding to a signal transmitted from the PA to a respective antenna element, to a second current. The device can convert a reflected voltage corresponding to a signal reflected from the respective antenna element, to a third current. The device can convert the first current, the second current, and the third current to an output voltage at a generator output. The device can further have a controller that can adaptively generate codebooks for transmission based on the output voltage.
