This report covers the design analysis of an Ericsson W-CDMA/LTE 2100MHz RRUS12 B4 2x60W remote radio unit. This unit is part of the RBS6601 main/remote base station platform for Ericsson supporting GSM/W-CDMA/LTE. The unit was manufactured in Q4 2013. Key Findings: The remote radio unit uses an innovative heat dissipation system to keep the high power amplifiers from overheating. Ericsson has switched to a new transceiver architecture that increases integration of semiconductor and passive components to reduce overall system size.
