Spectrum Signal Processing’s SDR-3000 Solutions Selected for US Military Communications
Development Programs

Burnaby, B.C., Canada — December 8, 2005 — Spectrum Signal Processing Inc., today announced that it’s flexComm™ SDR-3000 product family has been selected for two different military communications programs by a leading US defense contractor.

In the first program, Spectrum’s flexComm PRO-3500 basedband processing engine will be used for the development of a Software Communications Architecture (SCA) compliant waveform. This waveform will be used for a next generation military satellite communications (MILSATCOM) system designed to provide simultaneous voice, data and video communications for US and Allied forces anywhere in the world. This SCA compliant waveform will be able to operate on Joint Tactical Radio System devices.

Under the second program, Spectrum has delivered its flexComm SDR-3000 SMRDP, an integrated “RF to Ethernet” subsystem, to be used as part of a broader communications system under a classified program.

“We continue to get designed into advanced communications systems by leading defense contractors. These customers require our industry leading software defined radio solutions including the associated software stacks; notably the SCA and quicComm™, our proprietary hardware abstraction layer,” said Pascal Spothelfer, Spectrum’s President and CEO. “Our modular solutions are suitable for a wide spectrum of communications systems ranging from larger, high bandwidth MILSATCOM systems to small rugged devices, which we are now able to capture with our newly launched SDR-4000 product series.”

Spectrum’s flexComm PRO-3500 is a CompactPCI®-based Freescale™ G4 PowerPC® processing engine designed to work as the base-band processing engine in the company’s SDR-3000 series of software defined radio platforms.

The modified SDR-3000 SMRDP provides a turnkey black-side “RF to Ethernet” processing system and includes sample application software supporting frequency agile operation. The systems are comprised of Spectrum’s SDR processing and high-speed transceiver boards (PRO-3500 and XMC-3311) in a single-slot 2U CompactPCI chassis. These components are integrated with the Digital Receiver Technology, Inc. DRT2110 RF transceiver subsystem consisting of a tuner, an exciter and a single-board computer, in a 20-slot 3U CompactPCI chassis. The system also includes all software application libraries, including digital down-conversion and digital up-conversion field programmable gate array cores, operating systems and a SCA Core Framework. A comprehensive data flow example is provided as a starting point for customers’ design efforts.
