Filtronic, an AIM listed electronics manufacturer, has secured one point two million pounds in funding through the UK Space Agency’s National Space Innovation Programme. The award will support the development of a high power five hundred and fifty watt Ka Band Solid State Power Amplifier, referred to as the 550W Ka Band SSPA. The Filtronic space technology project centres on integrating this amplifier into existing satellite ground stations.
The new system is designed to provide a plug and play transition from older Travelling Wave Tube Amplifier equipment. It builds on Filtronic’s established SSPA design and targets a frequency band considered vital for modern satellite communications.
Ka band plays a key role in the growth of non geostationary constellations. These constellations use it for high capacity and low latency feeder and user links. Its wider adoption is linked to next generation services, including in flight connectivity and 5G Non Terrestrial Networks.
Nat Edington, chief executive at Filtronic, said: “This award reflects the strength of our innovation pipeline and our place in the UK’s space ecosystem. The 550W Ka-Band SSPA is a significant step change in solid-state performance, offering leading linear power in a TWTA-compatible form factor.
“It will enable operators to transition from travelling wave tube systems with reduced operating expense and enhanced reliability, helping to support more sustainable and future-ready satellite networks. Built on strategic industry partnerships and a proven record of innovation, our integrated design and manufacturing model delivers scalable, cost-efficient solutions that earned us selection under this leading programme.”
The Filtronic space technology project aligns with wider UK strategic aims for commercial space development. Dr Craig Brown, investment director at the UK Space Agency, said: “Filtronic’s project is a great example of the ambition behind the National Space Innovation Programme, turning cutting-edge UK research into commercially viable solutions that strengthen our global competitiveness. By advancing high-power solid-state amplifier technology, this project not only supports more resilient satellite networks but also accelerates the UK’s journey towards a sustainable and innovative space economy.”
Filtronic is headquartered in Sedgefield in Durham, with additional bases in Leeds, Manchester and Cambridge. The Filtronic space technology project therefore supports both technological development and regional industrial activity within the UK.
