Digital IF Products
Next generation all-digital architecture for communication systems
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 following standards:
- Future Advanced SATCOM Technologies (FAST) Open Standard Digital IF Interface (OSDI) (TIA/ANSI 5041); and
- Digital Intermediate Frequency Interoperability (DIFI) Standard (IEEE-ISTO Std 4900-2021).
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-FW-DIFI-XXX
DIFI FIRMWARE
IP CORe
The DIFI Firmware IP Core enables Digital Modem developers to mitigate risk in development of Digital Intermediate Frequency Interoperability (DIFI)-compliant equipment. AMD/Xilinx cores and engineering integration support are available.
WS-SYS-DIVA-DIFI-100
DIFI Digital IF Vector Analyzer (DIVA-D)
DIVA-D eases verification of compliance with the Digital Intermediate Frequency Interoperability (DIFI) Digital IF standard and provides continuous real-time monitoring of Digital IF traffic, including classification of packets.
