5G FR2 Beamformer Tool

Built for Beamforming Education

The BBoard is a beamforming educational tool that helps university professors save time and effort in courseware preparation. By adjusting the phase and the gain of each RF channel and observing the result on instrumentation, students can establish the connection between the theory and the real world.

Built for Research

The antenna engineers utilize BBoard to verify their designs; communication developers demonstrate the protocol and beam management algorithm via true mmWave beamformer. 

Optional accessory AA Kit (Array Antenna Kit) works perfectly with BBoard for students and engineers to obtain more insights about beamforming.

Beamforming Education Tool with UI

Software-controllable phase shifters offer 5.625 deg resolution and make BBoard a versatile beamformer. BBoard combines four RF ports with one COM port. By connecting an array antenna, BBoard turns into a full-fledged phased array and mimics the antenna used in UE.

API included compatibility with LabVIEW, Matlab, Python, C#, C++, and other programming languages.
