Multi-Carrier MS-DPD Development Platform Streamlines Base Station Design Process

NORWOOD, Mass. -- (BUSINESS WIRE)-- Analog Devices, Inc. collaborated with Xilinx Inc. to introduce a radio architecture development platform that helps multi-carrier cellular base station manufacturers reduce engineering resources and improve time to market.

ADI’s MS-DPD (mixed-signal, digital pre-distortion) development platform simplifies the wireless infrastructure design process by allowing OEMs to quickly assess and reprogram the radio to remove non-linearities from the transmit paths and enhance radio power efficiency.

ADI’s MS-DPD platform incorporates a high-performance RF and mixed-signal transmit and observation receiver chain supporting 2G, 3G and emerging 4G wireless protocols. Xilinx’s Virtex-6 FPGA ML605 (field-programmable gate array) Evaluation Kit connects to the MS-DPD board through an industry-standard VITA-57 FMC connector. Using this system, the FPGA can be used to implement required radio algorithms leveraging the ADI signal chain available on the MS-DPD.

“In collaboration with Xilinx, customers now have everything needed to demonstrate the transmit section of a base station radio,” said Martin Cotter, segment director, Communications Infrastructure, Analog Devices.

“ADI has combined high performance transceiver components into a single development platform for speeding the evaluation of critical DPD algorithms running on Xilinx’s Virtex-6 ML605 Evaluation Kit. The MS-DPD platform allows our customers to focus on differentiating their DPD algorithm from their competitors’ solutions.”

With the highest dynamic performance in its class, the multi-carrier MS-DPD development platform simplifies component selection and board layout to make it easier for designers of multi-carrier GSM and multi-standard SDR (software-defined radio) base stations to develop FPGA-based DPD algorithms. FPGAs also provide the flexibility to optimize the solution that competing fixed-function ASICs (application-specific integrated circuits) cannot, while providing a highly integrated, low cost, low power and high reliability solution to present day base station needs.
