Hello,
Hope you are doing well. I apologize for the inconveniences, but these ICs are under NDA. The only public available information about the UWB products is the one published on the public web page: Secure Ultra-Wideband (UWB).
If you are interested in testing these devices, you would need to check one of these Development Kits or Modules (UWB Developer Resources), and if you are interested in any particular Kit/Module, you would need to go directly with the Module Maker to know the process and the support that they can provide you.
Regards,
Ricardo
