Broadband Satellite Communications Supported by Spectrum's SDR-4000 SWM "IF-to-Ethernet" Wireless Modem
]
Spectrum's flexComm™ SDR-4000 SWM Satellite Communications (SATCOM) Wireless Modem (SWM) supports black-side "IF-to-Ethernet" digitization and processing of complex waveforms and provides modem, link and network layer processing functionality for a network-centric IP-based SATCOM system. The SDR-4000 SWM has been architected to support the latest in SATCOM waveforms including:
- Digital Video Broadcast (DVB/DVB-S2, DVB-RCS)
- INMARSAT BGAN
- Multi-User Objective System (MUOS)
The SDR-4000 also supports traditional legacy satellite waveforms such as the Intelsat Business Services (IBS) waveform following Intelsat Earth Station Standards 309 and 315 (IESS-309, 315).
The SDR-4000 SWM supports two analog input channels and one analog output channel supporting industry standard 70 and 140 MHz IF. External interfaces include Gigabit Ethernet, RS-232 and JTAG and a high-speed sample clock input. The SDR-4000 SWM employs a combination of two Xilinx® Virtex™-4 field programmable gate arrays (FPGAs), a Texas Instrument TMS320C6416T digital signal processor (DSP) and a Freescale™ MPC8541E general purpose processor (GPP) to provide the processing resources required to support the target waveforms.

Spectrum FPGA Processor Module Offers Higher Performance Processing with Deep Memory for Signals Intelligence Applications
]
Spectrum's XMC-8131 reconfigurable parallel processing engine provides high performance processing that supports the implementation of multi-channel, multi-mode receivers for both narrowband and wideband air-interfaces. The XMC-8131 is Spectrum's next-generation processing module that utilizes a single user-programmable Xilinx® Virtex-4™ FPGA that provides up to 152,064 available logic cells. The module offers two banks of 256 MB DDR2 SDRAM totaling 512 MB, ideal for signals intelligence (SIGINT) applications that require a large memory buffer. In addition to the increased processing capability, the use of the Virtex-4 component reduces the power consumption and price of the module over the previous generation product.

Spectrum Expands Software Radio Offering with Military and Satellite Communications Waveform Physical Layer Software
]
One of Spectrum's significant announcements in 2007 was to offer highly optimized air interface protocol stacks pre-integrated with its portfolio of software reconfigurable wireless solutions.
Spectrum announced its intent to offer physical layer implementations of military communications (MILCOM) and satellite communications (SATCOM) waveforms, including key U.S. Joint Tactical Radio Systems (JTRS) and NATO waveforms, as part of its SDR portfolio of products and services. Spectrum has teamed with industry leaders in the development of waveform technology to provide a selection of key waveforms and waveform components that have been pre-ported to Spectrum's modem platforms. This allows Spectrum to deliver integrated solutions that significantly reduce technical risk, development cost and time to deployment in its customers' radio programs.
This was followed shortly by the availability announcement of two waveforms:
- Wideband Networking Waveform (WNW) OFDM physical layer: L-3 Communications Nova Engineering's implementation of this U.S. JTRS next-generation, high data rate military waveform on Spectrum's SDR-4000 platform
