3.1 DU Configuration
DU is created as one enclosure, and has a mounting bracket on the back side for wall installation.
The DU receives 5G base station signal wirelessly and converts into IF frequency(Downlink). Also, it
converts the IF frequency into 37GHz RF signal through coaxial cable, and radiates the 5G signal to
the base station through antenna.
DU is configured with DPSU, DBTU, mmWave Module, DCPU module, and is supplied from the
MDU 37V power through the SISO port. And for system grounding the side is configured with AWG 6
ground terminal.
Figure 2. DU Configuration.
Warning
Since the DC 37V applied through Bias-T must be input through SISO port, SISO and MIMO
must be correctly distinguished when connecting coaxial cable.
