We've recently designed, built, and tested a 6U VPX microwave module for a high performance radar system with state of the art residual phase noise performance. The module was tested with our Holzworth Phase Noise Analyzer. Residual phase noise of <-155 dBc/Hz at 1 KHz offset and <-162 dBc/Hz at 10 KHz offset were acheived. Spurious levels were <-130 dBc. Internal detectors provided input and output detected power levels for Built-in-Test reporting. This module was tested using our in-house vibration, temperature, and shock qualification equipment.
