High-performance RF, electronic warfare, and radar subsystems

Aerospace & defence

Filtronic design, and manufacture complex transmit and receive modules (TRMs), filters and other RF components and sub-systems for aerospace and defence applications. We also provide contract manufacturing services for clients, producing and testing their precision components at scale to individual specifications in our state-of-the-art facilities.

When we design, develop and manufacture RF, microwave or mmWave components for defence applications, we work collaboratively with clients to build trust, communicate openly, ensure compliance, and deliver exemplary products that provide reliable, best-in-class performance.

We have a proven performance record and a continuous improvement culture, currently providing a range of market-leading contract manufacturing services to some of the globe’s largest defence primes. We are considered an integral supply chain partner, recently winning an award for outstanding supply chain contribution.

Long-term partnerships built on excellence
Our mission is to build sustainable partnerships with our clients in the defence and aerospace sector. We commit to the long-cycle collaborative development processes that are necessary before any volume manufacturing can begin. Our world-leading design and engineering expertise, state-of-the-art microelectronic manufacturing facilities and rigorous testing capabilities deliver technically advanced RF components and sub-systems across multi-year programmes.

High-performance defence & aerospace technology
Filtronic has invested in full turnkey manufacturing operations to produce intricate components at high-volume at our UK site. For the aerospace & defence industry, we design, manufacture and test products for a range of advanced sub-systems, including:

  • Radar (AESA type) – fire control, target acquisition and high-resolution imaging.
  • Electronic warfare (EW) and electronic countermeasures (ECM).
  • Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) – multifunction RF systems, satellite constellation, anti-access area denial (A2/AD).
  • Unmanned systems and counter unmanned systems.
  • Ultra-wide band digital systems.
  • Co-site interference mitigation.
  • Avionics.

Solutions for the full RF spectrum

Our engineers are world-leading RF experts, working with clients to solve complex problems across the full spectrum of RF, microwave and mmWave systems. The products we design and manufacture for aerospace and defence applications include:

Transmit and receive modules (TRM)
TRMs are used in electronically scanned radar systems, we have a track record of delivering high performance TRM’s used in AESA radars. We have been manufacturing TRM’s since 2011 and have a capacity for over 8,000 units per month.

RF filters
We have extensive expertise in developing microwave filters. Our products include metal cavity filters, ceramic, combline, interdigital, lumped element, suspended substrate, waveguide and thin-film filters. We are experts in filter topology, offering rapid prototyping and reduced development cycles.

Front-end modules
We design and manufacture fully integrated complex front-end switching and up/down conversion modules over a wide frequency range, up to and including mmWave.

Switched filter banks
Filtronic are experts at integrating filter and switch components in a single module minimising loss between circuits.
