Abstract :
A wide range of Radio Frequency (RF) assemblies require testing during their development and production. These include amplifiers, mixers, filters, up converters, down converters, antennas, phase shifters, power dividers, power combiners, Integrated Master Assemblies (IMAs), Weapons Replaceable Assemblies (WRAs), Line Replaceable Units (LRUs) and radio subassemblies. Though there are many differences between the RF assemblies, they all require a test system that is accurate, reliable and traceable while simultaneously minimizing test times. Other important attributes of a test platform for RF assemblies are that it must be calibrated, fully-characterized and incorporate self-test functionality. The test platform must also include a digital control solution for triggering, communicating with Units Under Test (UUT) and interfacing with handlers, fixtures, etc. Finally, the software for the test equipment must also be considered. Typical software functionality would include sequencing, reporting, testing, calibration, and self-test. While it is certainly possible to develop a test system specific to each type of RF assembly; there are many benefits to developing a common RF test platform that includes the functionality listed above.
