Design Analysis Ericsson GSM/W-CDMA 900MHz RUS01 B8 60W RF Transceiver Module
EJL Wireless Research, Nov 2011, Pages: 114
This report is a design “teardown” analysis of an Ericsson 900MHz Band 8 radio unit multi-standard (RUS) supporting GSM/W-CDMA technologies. The analysis covers the entire system including the power supply, transmit, receive, amplifier and duplexer filter functions. A simplified mechanical analysis of the unit along with detailed bill of materials analysis is presented in this report. The Ericsson product name is RUS01 B8. The Ericsson P/N for this RUS is KRC 118 62/1 R2C.
This report covers the design analysis of an Ericsson GSM/W-CDMA 900MHz RUS01 B8 60W RF transceiver/power amplifier/duplexer filter unit. This unit is part of the RBS6101/6102/6201/6202 base station platform for Ericsson supporting GSM/W-CDMA/LTE. The unit was manufactured in Q1 2011.
Key Findings:
- The module combines the RU22 and FU21 units of the prior generation RBS3000 BTS architecture and is similar to the DRU of the RBS2000 BTS architecture.
- Ericsson has switched to a new amplifier design and mounting system for the high power RF transistors.
- The TRx design is similar to the Ericsson RU22 design.
