RF, electronic warfare and AESA radar sub-systems


Unmatched excellence across the RF spectrum

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

From our award-winning base in the UK, we have a track record of delivering innovative early TRL projects as well as COTS products at high volume. We are an agile SME, who works collaboratively with our customers, acting as their high-frequency RF partner to deliver high-performance, high-reliability RF components and sub-systems.  

Our track record means we have developed and built complete trust, we communicate openly, ensure compliance, and deliver exemplary products with class leading Size, Weight and Power, minus cost that provide reliable, best-in-class performance.

Transmit and receive modules

Our transmit and receive modules (TRM’s) are traditionally used in electronically scanned radar systems. Transmit and receive modules provide amplification and electronic beam steering and can be applied in radar or communication systems requiring a steerable antenna. Our engineers have the experience and capability to design and manufacture our...

Front end modules

Front end modules are one of the most important parts of a RF System, Filtronic has extensive experience in creating high performance modules that are placed between the antenna and the digital baseband section of a wireless system. Front end modules are available in various configurations based on the...

Custom filters

Filtronic has extensive knowledge and expertise in the design, development and production of custom filters that dates back to 1977. Our custom filters 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...

Switched filter banks

Switched Filter Banks consist of a combination of switches and filters integrated into a single module. Integrating filter and switch components in a single module eliminates transitions between circuits, providing for optimal matching. Filtronic devices improve overall performance, including better insertion loss, flatness and voltage standing wave ratio (VSWR)....
