CHELMSFORD, Mass., 26 Feb. 2012. Mercury Computer Systems Inc. (NASDAQ:MRCY) in Chelmsford, Mass., is introducing two Express Mezzanine Card (XMC) modules -- the Echotek series RFM-251-XMC tuner, and the wideband ACM-V-XMC digital transceiver -- to capture signals in real-time across a wide range of frequencies for electronic warfare (EW) and signals intelligence (SIGINT) applications. The XMCs are available in ruggedized versions.

The small-form-factor embedded computing RFM-251-XMC tuner supports a frequency range from 20 MHz to 2.5 GHz, converting detected signals to digital IF. The IF is pre-digitized via a high fidelity analog-to-digital converter and routed onto a Virtex-6 field-programmable gate array (FPGA) for filtering and protocol processing.

The ACM-V-XMC digital transceiver combines a wideband analog-to-digital converter with a fast digital-to-analog converter and dual Virtex-6 FPGAs. It features direct digitization of L-Band signals and can operate as a high-speed transceiver for embedded computing applications in military embedded systems.

"The RFM-251-XMC Tuner features a high dynamic range, low phase noise and fast tuning speed that support a very high probability of intercept, and the Wideband ACM-V-XMC Digital Transceiver's ultra-high-speed digitizer and on-board FPGA excel at signal processing and data movement," says Ian Dunn, vice president of Mercury's microwave and digital solutions group.
