Our History
From our founding to RF technology leader

Early beginnings and founding

Filtronic was founded in 1977 by Professor David Rhodes, a pioneering engineer with a vision to transform RF and microwave technology. Initially specialising in filters and related components for the defence industry, the company quickly adapted as mobile communication surged in the 1980s. Filtronic became a key player in the evolving cellular network landscape, supplying high-performance filters that proved essential to its rapid expansion.

Expansion and innovation in telecommunications

Throughout the 1990s, Filtronic experienced rapid growth, expanding its product portfolio, acquiring several key organisations, and entering the FTSE 250 for the first time. During this period, Filtronic acquired Fujitsu’s Silicon DRAM plant in Newton Aycliffe, located in the North East of England, and transformed it into the largest GaAs foundry in Europe, capable of producing 6-inch GaAs wafers.

Breakthroughs in millimeter-wave technology

In the early 2000s, Filtronic made significant strides in millimetre-wave technology, which would later become critical for applications such as 5G and satellite communications. The company’s groundbreaking work in E-band transceivers enabled higher data rates and increased bandwidth, setting new industry standards for wireless backhaul and point-to-point communication. Filtronic’s expertise in this area positioned the company at the forefront of next-generation communication networks.

Diversification into high-performance markets

As Filtronic continued to innovate, the company diversified into other high-performance markets, including Aerospace, Defence, Critical Communications, and Space. Leveraging its deep knowledge of RF and microwave engineering, Filtronic developed robust, mission-critical components and sub-systems for radar, secure communication networks, and satellite infrastructure. This diversification not only broadened Filtronic’s market reach but also demonstrated the versatility and reliability of its technologies in some of the most demanding environments.

Leading the future of connectivity

Today, Filtronic stands at the forefront of RF, microwave, and millimetre-wave technology, driving the next generation of global connectivity. The company continues to push the boundaries of innovation, delivering cutting-edge solutions that accelerate the deployment of 5G networks, enhance mission-critical communication systems, and advance the capabilities of satellite communications (SatCom). With a legacy of innovation and an unwavering commitment to excellence, Filtronic is well-positioned to shape the future of wireless communication for generations to come.
