Filter contract comes from down under

Isle of Wight, England: RF Engines (RFEL), specialists in signal processing for FPGAs, were awarded a contract by Australia’s Defence Science and Technology Organisation (DSTO) to provide high-performance digital filter designs. The designs, which play a role in an advanced receiver systems, will use RFEL’s existing portfolio of signal-processing intellectual property (IP) to deliver quality filtering of wideband signals in real time.

RFEL will supply DSTO with two filter designs, each based on frequency-domain filtering techniques that use the polyphase DFT. The first design will support a continuous complex sample rate of 200MHz with 512 frequency-domain weights, whilst the second design will support complex samples rates over 150MHz with 4096 weights.
