A Significant Advancement in Signal Processing

Fidelity Improvement at Reduced Cost

Imagine a world where antennas no longer require co-location with the baseband equipment. Improved link availability, traffic distributed across multiple terminals, additional freedom in the modem set installed for a particular terminal... now stop imagining. That world is here. Welkin Sciences' Digital IF products enable more flexible switching and routing while also improving signal fidelity, with potential for reduced costs.

Compliant with Current Standards

Welkin Sciences' Digital IF products are compliant with the Future Advanced SATCOM Technologies (FAST) Open Standard Digital IF Interface (OSDI) (TIA/ANSI 5041).

Digital IF Products

WS-SYS-DCS-125M-200

Digital conversion subsystem (DCS)

DCS provides digital conversion of standard analog L-band interfaces in the uplink and downlink paths (125 MHz of aggregate bandwidth in each direction). The interface to the WSP is via Ethernet fiber optic links.

WS-SYS-WSP-6S-200

Wideband Signal Processor (WSP)

This real-time processor for Digital IF applications processes quadrature baseband signal samples for compatibility with Digital Modems and/or Legacy Modem Data Converters.

WS-SYS-LMDC-200

Legacy Modem Data CONVerter (LMDC)

LMDC is the technology transition product that provides the interface between legacy analog L-band modems and modern Digital IF terminals.

WS-FIFC

FAST Interface Firmware Core (FIFC)

FIFC enables Digital Modem developers to mitigate risk in development of FAST-compliant equipment. Xilinx and Intel/Altera cores are available. Engineering integration support is also available.

WS-SYS-DIVA-100

Digital IF Vector Analyzer (DIVA)

DIVA eases verification of compliance with the TIA-5041 Digital IF standard and provides continuous real-time monitoring of Digital IF traffic, including classification of packets.
