Design Analysis Ericsson WCDMA 2100MHz RRU22 21IV40 40W Remote Radio Unit
EJL Wireless Research, Nov 2010, Pages: 83
This report covers the design analysis of an Ericsson WCDMA 2100MHz RRU22 21IV40 40W Remote Radio Unit. This unit is part of the RBS3418/3518 WCDMA base station platform for Ericsson. The unit was manufactured in Q1 2008.
Key Findings:
- The RF power amplifier uses a unique combiner technology and the there is a dual transmitter design used.
- Ericsson used an extremely compact third party power supply solution for the RRU.
- The TRx is similar to the Ericsson RU22 design
- Custom VCO modules are used for the transmit and receive timing
