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 Digital Intermediate Frequency Interoperability (DIFI) Standard (IEEE-ISTO Std 4900-2021).

Digital IF Products



The DCS-D 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. Transport of the digital data conforms to IEEE-ISTO Std. 4900-2021, ver. 1.1.



The DIFI IP Firmware 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.


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.
