Abstract
A method for operating a phase shifter chip RF self-test. The method includes outputting, by control hardware, a first signal from a phased locked loop to a pre-amplifier and an input peak detector, outputting, by the control hardware, a second signal from the pre-amplifier to a device under test, selecting, by the control hardware, a target level, and adjusting, by the control hardware, a pre-amplifier gain of the pre-amplifier to cause the input peak detector value to approximately match the target level. The input peak detector is configured to output an input peak detector value based on the first signal.
