Lightweight High-Performance Signal Filters for Next-Gen Satellites and 5G Space Networks

digitalPilotedTRL 7

Imagine a tiny, high-tech sieve that only lets specific radio signals through while blocking all the noise. Instead of using heavy, bulky metal parts, this tech uses a special thin-film material similar to what's in smartphones. It makes satellite communication equipment much lighter and more stable, even in the extreme temperatures of space.

The business problem

What needed solving

Satellite operators currently rely on bulky mechanical filters or non-European technology, which increases launch mass and creates supply chain vulnerabilities for 5G NTN networks.

The solution

What was built

A new Surface Acoustic Wave (SAW) filter technology using Piezo-On-Insulator (POI) substrates. This includes dual L+S-band filter designs and prototypes tested in QFN packaging.

Who can put this to work

Satellite Communications
enterprise
Target: LEO Satellite Constellation Operator

If you are a constellation operator dealing with the high cost of launching heavy equipment — this project developed POI-based SAW filters that reduce mass and replace bulky mechanical filters. This allows for more hardware per launch and better thermal management in orbit.

Telecommunications
enterprise
Target: 5G Non-Terrestrial Network (NTN) Provider

If you are a network provider dealing with the need to integrate satellites into 5G networks — this project developed dual L+S-band filter solutions. This ensures high rejection and low signal loss for broadband digital connectivity.

Aerospace Components
mid-size
Target: RF Component Manufacturer

If you are a manufacturer dealing with dependence on non-European critical technologies — this project developed a European-based supply chain for POI wafers and back-end processing. This secures the production of high-reliability RF passive components.

Frequently asked

Quick answers

What is the estimated cost or price of these filters?

Based on available project data, specific pricing is not mentioned, but the project aims to reduce costs by replacing bulky mechanical filters with integrated POI-based solutions.

Can this technology be produced at an industrial scale?

Yes, the technology leverages POI wafers already produced for the smartphone industry and targets all volume demands from GEO to LEO satellite constellations.

Who owns the IP and how is licensing handled?

Based on available project data, the value chain includes a consortium of 5 partners including SOITEC SA; however, specific licensing terms are not disclosed.

How does this integrate into existing satellite hardware?

The filters are designed for high integration and are being tested in QFN packaging to ensure they fit into active antenna modules.

What is the timeline for market availability?

The project runs from 2023-01-01 to 2026-03-31, aiming to reach TRL7 by the end of the period.

Consortium

Who built it

The consortium is heavily industry-driven with an 80% industry ratio, consisting of 4 companies and 1 university across 3 countries (FR, BE, ES). Led by SOITEC SA, the group integrates the entire value chain from wafer supply and device optimization to space reliability testing (ALT) and system integration (TAS), indicating a strong push toward commercialization rather than pure research.
