Design Analysis Ericsson WCDMA 2100MHz RRU22 21IV40 40W Remote Radio Unit

Description:
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

Component and semiconductor suppliers mentioned in this report include: Analog Devices, Altera, Anaren Microwave, ATC, Atmel, Avago Technologies, Coilcraft, Epcos AG, Epson Toyocom. Fairchild Semiconductor, Freescale Semiconductor, Fujitsu Microelectronics, Hittite Microwave, Infineon Technologies, Integrated Device Technology, International Rectifier, Linear Technology, M/A-COM, Maxim Integrated Products, Micron, National Semiconductor, NDK, Nippon Chemi-Con, NXP Semiconductors, ON Semiconductor, RF MicroDevices, Skyworks Solutions, STMicroelectronics, Texas Instruments, TriQuint Semiconductors and Xilinx.
