    Development of generic test algorithms for broadband RF and microwave components can be challenging due to the wide variances in device properties. Test assumptions, which are suitable for devices with tightly constrained setup and operating ranges, tend to break down when generalized to the broader population of microwave devices. These difficulties are compounded when dealing with high power com... View full abstract»
