What we do

Data keeps the modern world running, from laptops to cars—but as demand grows, moving that data efficiently is becoming more challenging. At Filtronic, we specialise in keeping connections seamless, with higher bandwidth, lower latency, and rock-solid reliability. That’s why leading global companies turn to us for solutions they can’t find anywhere else.

Whether at work or at home, we all rely on RF signals—and whole industries depend on fast, reliable wireless connections. With the RF spectrum being limited and increasingly complex, Filtronic helps technology companies make the most of it, keeping the world better connected.

Our technology is trusted in high-performance sectors like aerospace, defence, telecoms infrastructure, critical communications, space, and beyond.

At Filtronic, we’re driven by excellence, integrity, and respect. We push the boundaries of technology while staying true to our values, collaborating to create innovative solutions that solve today’s challenges and shape tomorrow’s world. By building strong partnerships and focusing on sustainable growth, we’re committed to making a lasting impact.

Where we lead

Eband

E band represents the frequency range from 60 GHz to 90 GHz. Demand for E-band mmWave radio links is growing rapidly, as they can provide high capacity and low latency XHaul for the latest 5G networks that are being rolled out globally. Filtronic’s device-agnostic Microwave and mmWave transceivers, offer high-performance, are competitively priced and significantly reduce client time to market. Our ultra-high-capacity E-band (71-76 and 81-86 GHz) mmWave transceivers are designed to deliver cost-effective, carrier-class multi-gigabit connectivity for mobile backhaul networks.
