Analog Devices (ADI) and Xilinx announced the MS-DPD (mixed-signal, digital pre-distortion) development platform. MS-DPD helps multi-carrier cellular base station manufacturers reduce engineering resources and improve time to market. 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. The ADI MS-DPD development boards are available now for $3,995 each.

ADI’s MS-DPD development board features a RF and mixed-signal transmit and observation receiver chain supporting 2G, 3G and emerging 4G wireless protocols. The radio architecture development platform simplifies the wireless infrastructure design process by enabling OEMs to quickly assess and reprogram the radio to remove non-linearities from the transmit paths and enhance radio power efficiency.
The mixed-signal, digital pre-distortion 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.
