Spectrum Announces Next-Generation Software Defined Radio Products for Deployment in Harsh Tactical MILCOM Environments

ATLANTIC CITY, NEW JERSEY--(CCNMatthews - Oct. 18, 2005) - Spectrum Signal Processing Inc. (TSX:SSY)(NASDAQ:SSPI) -

SDR-4000 now available for high volume small form factor applications

Spectrum Signal Processing Inc. today announced at MILCOM 2005 the launch of its SDR-4000 rugged 3U CompactPCI® line of software defined radio (SDR) solutions. The SDR-4000 flexComm™ product family leverages proven SDR-3000 technology, integrating high-performance commercial-off-the-shelf (COTS) hardware, software and services for the development and deployment of black-side wireless modem solutions for tactical military communications (MILCOM) systems. It includes a high-speed dual transceiver module and high-performance processing engine available in conduction or air-cooled versions suitable for both harsh and benign environments. The SDR-4000 is tested in accordance with military standard MIL-STD-810 ensuring it is ready for deployment in many applications requiring ruggedization. The 3U cPCI form factor and flexible design make the SDR-4000 ideally suited for volume production.

Architected specifically for rugged tactical MILCOM applications, the SDR-4000 delivers high-speed, low latency deterministic data through an innovative product design that combines heterogeneous processing elements, high-speed communication fabrics and a comprehensive software environment suitable for Software Communications Architecture (SCA)-compliant waveforms.

"We designed the SDR-4000 as a tactical MILCOM solution that our customers can take from their lab to the field," said Mark Briggs, Spectrum's Vice President of Marketing. "Developers can immediately deploy our off-the-shelf SDR-4000 offering, while concurrently leveraging Spectrum's engineering services to refine the product to meet their precise size, weight, power consumption and production cost targets. This optimization service is part of Spectrum's modified COTS program, that is crucial for meeting the specific needs of harsh environments and large scale production."

"The SDR-4000 product family was developed to meet the needs of defense customers who are demanding smaller, more power-efficient systems in the field and is a logical extension to our SDR-3000 product line," said Pascal Spothelfer, Spectrum's Chief Executive Officer. "By offering the market a deployable rugged solution we are advancing in lock step with the SDR tactical MILCOM market, which is moving from the development stage to the field trial and deployment stages. Having already delivered this industry leading product to multiple customers puts us in a very strong position in this market."

The two main hardware components within the SDR-4000 series are the PRO-4600 SDR modem processing engine and the XMC-3321 dual-transceiver I/O mezzanine card. The system combines the processing power of the Xilinx® Virtex-4™, the Freescale® PowerQUICC™ III PowerPC™ and Texas Instruments' TMS320C64x™ digital signal processor elements into a single system. These three processors are required to implement the diverse set of waveforms typically employed in military communications systems. Together, these products provide a wireless modem that accommodates two channels per slot. The package includes Spectrum's quicComm™ software, a hardware abstraction layer that facilitates platform programming and code portability. For instance, quicComm allows applications developed on the SDR-3000 to be readily ported to the SDR-4000. Also provided are comprehensive software examples that demonstrate application data flows that simplify and accelerate development initiatives. Technical support services and training courses are part of this extensive product offering. Details on the SDR-4000 can be found at www.spectrumsignal.com/products.

The SDR-4000 is available for order immediately.
