BBoard
5G/B5G Beamforming Educational Kit
Build for Education
BBoard helps university professors save time and effort in courseware preparation. By adjusting the phase and the gain of each RF channels and observing the result on instrumentation, students can establish the connection between the theory and the real-world.
Build 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 .
mmWave Beamformer with GUI
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, compatible with LabVIEW, Matlab, Python, C#, C++ and other programming languages.
Unleash control with WEB-TLK. Effortlessly manage TMYTEK hardware through any web browser.
