Pentek Inc. in Upper Saddle River, N.J., is offering a digital receiver board with high-speed A-D and field-programmable-gate-array (FPGA) dual-channel digital downconverter. The model 6821-422 is based on the Model 6821 215 MHz A/D Converter VME with dual Virtex-II Pro FPGAs, and includes a wideband digital downconverter (DDC) IP core. The board features high-speed A-D with 12-bit sample rate at 215 MHz; GateFlow wideband digital downconverter FPGA IP core; preconfigured combination software radio subsystem; data-acquisition front end for DSP and recording systems; four sets of user-programmable FIR coefficients for custom filtering; and ruggedized and conduction-cooled versions available. Applications include wideband recording and systems, real-time DSP and software radio systems, and data-acquisition applications for wideband communication signals used in telemetry and satellite communications. Radar-pulse and beamforming applications especially benefit from the board’s many gate, trigger, and multichannel synchronization modes. For more information contact Pentek online at www.pentek.com.
