PathWave System Design 2022 Update 0.1 is a major release. It continues the focused effort on RF system modelling excellence, derived from Keysight’s measurement science leadership, and offers powerful connectivity to other enterprise tools, both Keysight and third-party, which drive digital mission engineering design flow.

PathWave System Design strives to make RF system simulation effective for all system engineers, working in RFIC, subassembly or mission / system-of-systems applications. It enables process flows between circuit design, RF system design, baseband design, and hardware verification through platform connectivity. Enhanced features for Aerospace Defense, Cellular, and Wi-Fi system designers are included, as well as updated RF system simulation capabilities.  Phased array analysis is further enhanced, including improved antenna and RF modeling.
