Digital Intermediate Frequency Interoperability (DIFI) Consortium

Our Mission

The mission of the Digital Intermediate Frequency Interoperability (DIFI) Consortium is to enable the digital transformation of space, satellite, and related industries by providing a simple, open, interoperable Digital IF/RF standard that replaces the natural interoperability of analog IF signals and helps prevent vendor lock-in.

About DIFI
