This report covers the design analysis of an Alcatel-Lucent WCDMA 850MHz 9341 40W Remote Radio Unit. This unit is part of the WCDMA base station platform for Alcatel-Lucent. The unit was manufactured in Q1 2009.

Component and semiconductor suppliers mentioned in this report include: Analog Devices, Anaren Microwave, ATC, Bourns, C-MAC, Coilcraft, CTS Corporation, Cypress Semiconductor, Epcos AG, Fairchild Semiconductor, Freescale Semiconductor, Fujitsu Microelectronics, GSI Technology, Hittite Microwave,  International Rectifier, Integrated Device Technology, Intel, Linear Technology, Marvell, Maxim Integrated Products, Micron, National Semiconductor, NXP Semiconductors, ON Semiconductor, RF MicroDevices, Skyworks Solutions, STMicroelectronics, Texas Instruments, TriQuint Semiconductors and Xilinx.

Key Findings:

- The RF duplexer filter size at 850MHz caused a redesign of the entire RRU casing resulting in special cover for the filter.

- Alcatel-Lucent used tamper proof TORX screws to prevent non-authorized user from opening the unit and discovering its secrets. This is the only vendor we are aware of using this screw technology for their products.

- Alcatel-Lucent is using its MCR radio transceiver architecture for its RRU product platform

- Custom VCO modules are used for the transmit and receive timing
