Spectrum's SDR-4000 WML Offers Solutions for Power Constrained Tactical Military Communication Deployments

Lite version of Spectrum's 3U cPCI wireless modem blade

WASHINGTON, DISTRICT OF COLUMBIA--(CCNMatthews - Oct. 23, 2006) - Spectrum Signal Processing Inc. (TSX:SSY)(NASDAQ:SSPI) today announced at MILCOM 2006 the availability of its flexComm™ SDR-4000 Wireless Modem Lite (WML), a lower power rugged package that supports the critical modem, link and network layer processing functions necessary in a software defined radio. The Lite version reduces the power required per slot by supporting a selective feature set from Spectrum's SDR-4000 products.

The SDR-4000 WML is specifically designed for tactical Military Communications (MILCOM) applications and provides black-side "IF to Ethernet" digitization and processing of complex waveforms. It consists of an XMC-3321 dual transceiver module mounted onto a 3U cPCI PRO-4600 Lite carrier card. The wireless modem has been architected to support waveforms requiring low latency deterministic operation to maintain synchronization on a frequency-hopped tactical MILCOM network. This is accomplished through the use of independent data and control fabrics throughout the SDR-4000 WML architecture, with high-speed data transferred from the XMC-3321 to the PRO-4600 Lite using Spectrum's low power Solano® communications technology.

"The SDR-4000 WML is targeted for applications deployed in size, weight and power constrained environments," said Mark Briggs, Vice President, Marketing at Spectrum Signal Processing. "Reducing the power consumption is essential for applications that have limited battery power such as unmanned vehicles and tactical data links."

The SDR-4000 WML is available in either an air-cooled or conduction-cooled configuration. It supports two IF input channels, two IF output channels, an internal or external 10 MHz reference and high speed sample clock, Gigabit Ethernet, RS232 and JTAG connectivity. The SDR-4000 WML employs a combination of processing devices, including a Xilinx® Virtex-4™ field programmable gate array, a Texas Instrument's TMS320C6416 digital signal processor and an MPC8541E general purpose processor.
