UD Box 5G
BB-UDC-5G-2444-0014-S / BB-UDC-5G-2444-0014-D

5G era is coming soon. Massive deployment is expected in 2021 worldwide. IMT-2020 defines eMBB,URLLC, and mMTC, which are keys to successful 5G communications. TMYTEK has developed ascalable and flexible system consists of BBox (a ready-to-use beamformer) and UD Box (an up/downconverter) to help our customers move onto 5G beamforming developments and tests with ease.
Our broadband UD Box comprises the mixer(s), internal LO built by our excellent phase noise PLO andoptional filters. More details are below.
