X微波设计系统
该产品可作为X-MicroWave块（X-MWblock）提供，用于评估。
x-mwblock.s are RF and microwave "drop-in" components that can be used individually for prototyping or in production assemblies. X-MWblocks are easy to test, integrate, align, and configure to 60 GHz and beyond. No messy sweat soldering or silver epoxy processes are required. X-MWblocks are highly characterized with S-parameter models and connect with a patented solder-less interconnect technology.
