RF over IP Digitisers

Digital IF is the technology that bridges the gap between the traditional RF technology and the evolving cloud virtualised ground segment.  

ETL’s Digital IF products plays a pivotal role in this transition by efficiently sampling analogue signals from diverse sources. These signals are then encapsulated as IP packets and transmitted over an ethernet connection, a process commonly referred to as ‘RF over IP’.

The signals are reconstructed at the receiving end, enabling seamless communication and data transfer between locations. This innovative approach not only streamlines signal transport but also facilitates the integration of traditional RF systems into modern digital infrastructures, marking a significant advancement in satellite communications technology.

The Digital Intermediate Frequency Interoperability (DIFI) Consortium aims to facilitate digital transformation in satellite and related industries through a simple, open, and interoperable DIF/RF standard. This standard replaces the inherent interoperability of analog signals and helps prevent vendor lock-in. Unlike analogue RF, DIF is modulation agnostic and requires no signal conditioning for IP data streams. ETL Systems has been instrumental in developing this standard as a board-level member of the DIFI Consortium.
