NSIP funding award to develop next generation high-power amplifier

New solution delivers leading linear power performance for future satellite
systems

 

Filtronic plc (AIM: FTC), the designer and manufacturer of advanced RF
solutions for the space, aerospace and defence, and telecoms infrastructure
markets, announces that it has been awarded £1.2m funding through the UK
Space Agency's National Space Innovation Programme ("NSIP") for a project to
develop a high-power 550W Ka-Band Solid-State Power Amplifier ("SSPA").

 

Designed to fit seamlessly into existing satellite ground stations,
Filtronic's new SSPA enables an easy, plug-and-play transition from older
Travelling Wave Tube Amplifier ("TWTA") technology.

 

This strategic development builds on Filtronic's successful SSPA design and
targets a critically important frequency band. Ka band is central to the
expansion of non-geostationary constellations, which rely on it for
high-capacity, low-latency feeder and user links. Its adoption is also
essential for enabling next-generation services, from in-flight connectivity
to 5G Non-Terrestrial Networks. As a result, Ka band will underpin many of the
high throughput Satcom services expected to shape the industry over the next
decade.

 

NSIP is a UK government initiative funding innovative space technology
projects and the Company's new high-power amplifier features in the
programme's, "Major Projects" category, a scheme designed to advance the
commercialisation of high-impact UK technologies, de-risk investment and speed
up the route to market.

 

Nat Edington, Chief Executive Officer at Filtronic commented: "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."

 

UK Space Agency Investment Director, Dr Craig Brown 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."
