Overview

The SDR-4002 MRSS is a rugged, conduction-cooled IF-to-Ethernet modem processing subsystem. The SDR-4002 MRSS architecture is cost-optimized for systems requiring multi-band and multi-channel RF/IF operation. It is an ideal platform for radio manufacturers and system integrators to meet the primary analog and modem processing needs of a variety of applications including radio gateways, tactical radio, and terminals. The SDR-4002 MRSS features a software reconfigurable processing engine, as well as multiple PHY/MAC layer and analog IF processing cards. The subsystem is designed to run a variety of legacy narrowband waveforms, as well as current generation ad-hoc networking and IP-centric waveforms.

The default SDR-4002 MRSS configuration supports four IF inputs and four IF outputs, with each supporting industry standard analog IF frequencies such as 21.4 MHz and 70 Mhz. It is comprised of a collection of 3U CompactPCI cards which include:

• One PRO-4600 modem processing card to handle PHY/MAC and network layer waveform processing functions
• Two PRO-4610 dual IF transceiver cards that provide integrated ADC/DAC interfaces to an external RF front-end assembly
• One system controller card that provides basic system control functions, external I/O interfaces, and built-in flash memory to store waveform and application components

Adding or removing PRO-4610 and PRO-4600 modules allows integrators and radio developers to easily scale the system to meet specific performance or channel capacity requirements.

Features

• High-speed serial full-duplex connectivity between PHY and MAC layer processing blades
• Incorporates FPGA, DSP and GPP software reconfigurable technology to support PHY and MAC layer processing of waveforms such as Wideband Networking Waveform (WNW), Soldier Radio Waveform (SRW), and Single Channel Ground and Airborne Radio System (SINCGARS)
• Rugged, conduction-cooled modem hardware immediately ready to be designed and deployed into your custom chassis or enclosure
• Supports interfaces for Absolute GPS timing reference, Push-to-Talk operation, Gigabit Ethernet, RF control, and MMI (Man-Machine-Interface)
• Supports Communications Research Canada (CRC) SCA SCARI++ SCA CF v2.2.2, and Spectrum’s high-performance API library, quicComm™
• Utilizes Green Hills® INTEGRITY® Embedded RTOS
• Supports analog IF frequencies including 70 MHz, 21.4 MHz, and IF Bandwidths of up to 30 MHz bandwidth, along with digital and analog control interfaces
• Pre-integrated and tested system controller, backplane, modem processing and analog IF modules that can be scaled in a cost effective manner

Benefits

• Rugged design to support deployment in harsh environments
• Enable interoperability between heterogeneous legacy and ad-hoc radio networks
• Replace multiple modems with a single software reconfigurable modem that can support multiple networks
