“Defence and space are high‑growth sectors with strong demand for UK‑based supply chains,” says Tudor Williams, Filtronic’s chief technology officer. A UK Government case study published on 12 March 2026 lays out what that looks like on the ground in County Durham. (gov.uk)

The engineering fix tackles a familiar headache in radar and electronic warfare: bulky ceramic packages around high‑power chips. Filtronic’s plastic Quad Flat No‑lead (QFN) design trims size and weight while keeping performance stable and heat under control. The programme finished in August 2025 after more than 150 devices were pushed through high‑moisture exposure, 500 thermal cycles and heavy electrical stress. Every unit passed its electrical tests.

In plain terms, a radar stack packed with hundreds of fingernail‑sized semiconductors can now deliver more power for less mass - a real gain when equipment is flown, sailed or mast‑mounted. That’s the difference a smarter package makes. (gov.uk)

The production is Northern, not London‑centric. Filtronic opened new manufacturing in the North East in 2025 and, on 27 February 2026, cut the ribbon on a 44,000 sq ft headquarters and manufacturing site at NETPark, Sedgefield - doubling UK production footprint and delivering a six‑fold jump in cleanroom space.

According to the UK Defence Innovation case study, the project’s impact is already visible: Filtronic has doubled its workforce, tripled revenue and secured UKRI follow‑on funding to push thermal performance even further. (gov.uk)

“By pushing devices to their limits and validating performance, we’ve taken a step forward in sovereign capability,” Williams adds - a succinct summary of why this matters for a UK‑based defence supply chain. (filtronic.com)

Backed by the Defence Technology Exploitation Programme (DTEP) run through UK Defence Innovation and DASA, Filtronic also worked alongside a major UK defence prime - a partnership that helped shape the brief and unlock board approval for the new line. (gov.uk)

There’s a commercial kicker too. Filtronic’s strategic partnership with SpaceX’s Starlink - signed in April 2024 and since followed by larger orders - puts North East engineering into a global network that moves serious volumes. (filtronic.com)

For the region’s suppliers, this isn’t abstract. Polymer moulders, leadframe specialists, toolmakers, thermal materials labs, automation integrators and test houses across the Tyne‑Tees corridor have a live opportunity to feed a packaging line that’s scaling here, not elsewhere.

This story also speaks to levelling up with substance. R&D conceived in the North is becoming higher‑value manufacturing, apprenticeships and export‑class product - and it’s happening without decamping to the capital.

What comes next is disciplined delivery. With capacity now in place at NETPark, Filtronic says it’s positioned to scale volume production for defence and space while keeping a dependable, on‑shore supply of high‑frequency components. (filtronic.com)

For Northern SMEs eyeing growth, the signal is clear: if you can help make this packaging faster, cooler or cheaper, there’s work to be won close to home.
