Bedford Signals Corporation Completes Preliminary Testing of RF Arbitrary Waveform Generator Array.
Burlington, MA - 2 July 2007 - Bedford Signals Corporation has completed unit testing of a new high performance DSP board. This board supports eight RF outputs, with a PowerPC and 4 FPGAs for control and signal processing. It is intended for high bandwidth high dynamic range applications, and will be used to demonstrate an eight channel version of our Hardware in the Loop GPS Jammer Simulator.
The board has eight Analog Devices 16 bit 300/1000 MSPS Dual AD9779 Digital to Analog Converters (DACs) to generate complex analog signals, and eight Hittite HMC497 modulators that up convert the baseband signals to RF. It is controlled by a Freescale MPC8540 PowerQUICC III processor, with four Xilinx Virtex-4 FPGAs (general purpose LX 160 or signal processing oriented SX55) for real time processing power. The FPGAs are interconnected by high speed parallel DDR LVDS buses. Clocks and the local oscillator are generated on board using an OCXO reference, but they can also be provided by external sources.
After the board completes performance testing, it will be available for use in new Research and Development projects. The board is suitable for Software Defined Radio (SDR) Multiple Input Multiple Output (MIMO) or Phased Array transmitter development. The on-board modulators support RF outputs from 100 to 4000 MHz.
Bedford Signals Corporation is a privately held company, established in May of 2003 to hurdle the challenges of high bandwidth Digital Signal Processing for Satellite and Terrestrial Communications Systems. Core competencies include communications systems, networks, and protocols - with a focus on sophisticated spatial and temporal array processing for wireless communications systems.
