Pair Teams On DPD Design Solution

A mixed-signal, digital-predistortion (MS-DPD) development kit from Analog Devices [3] will help wireless infrastructure equipment designers who need to quickly evaluate systems using DPD techniques in multicarrier cellular base stations. It is designed to seamlessly integrate one of the company's mixed-signal transmit chains of devices with any field-programmable gate array (FPGA) development kit with a high-speed mezzanine card (MSMC) connector from Altera Corp. [4] The Analog Devices development board contains more than a dozen of the company's components, including a high-speed digital-to-analog converter (DAC) and quadrature modulator. According to Martin Cotter, Segment Director, Communications Infrastructure, Analog Devices, "The MS-DPD platform offers the highest performance possible in the transmit and observation-path signal chains, allowing our customers to focus on differentiation in their DPD algorithm implementations."
