Where we lead


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.


Filtronic is a high performance expert with a track record of delivering transceiver solutions that lower the overall cost per Gbps. We are the partner of choice for leading OEMs and mobile network operators looking for bespoke, microwave and mmWave components and subsystems for XHaul applications.

Solid-state power amplifiers

Solid state power amplifiers (SSPAs) convert a low-power radio frequency signal to a higher power one. Filtronic’s range of power amplifiers provide market leading linear mmW power. Cerus is a series of E-Band (71 to 76 GHz) power amplifiers for point-to-point applications. They are ideal for military or commercial applications with excellent SWAP (low size, weight and high power) perfect for airborne & non-terrestrial applications.

Microwave Filters | Filtronic PLC


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

Looking to the future

Telecoms – making space for data

To manage forecasted data traffic, millimetre wave (mmWave) bands at the higher end of the frequency spectrum will need to be licensed for use by telecoms. The semiconductor processes and RF technologies required for W-band (92-115GHz) are well advanced – and will be ready by the time licences are granted. Work is underway to solve the fundamental challenges associated with D-band (138-174GHz), which offers much higher data rates, but requires significant changes to device architecture and manufacture.

Trackside to train – data on the move

The quest to provide reliable Wi-Fi on trains continues, and the UK has set targets for on-train data speeds. Creating high-data wireless environments on vehicles travelling at high speed poses significant technology challenges. Filtronic has developed a number of demonstration transceivers, which are now being trialled worldwide. These are successfully delivering E-band links to trains and could be commercially available in the next few years.

Critical communications

High frequency trading: gaining competitive advantage

High-performance private wireless networks are starting to be used to improve the competitiveness of high-frequency trading. Wireless point-to-point radio links can transmit signals milliseconds faster than fibre-optic cables. In such high-frequency trading where decisions are made by machine learning, the ability to make decisions a fraction of a second faster than the competition delivers a real competitive advantage.

Why Filtronic?

Filtronic has been at the forefront of RF communications for over 40 years.

Our product range and wider technology capabilities are supported by our IP and in-house knowledge, and we have an extensive patent portfolio. Our vision is to innovate and push the boundaries of what Is possible with RF, Microwave and mmWave communication, delivering transformative wireless solutions through design and manufacture leadership, connecting everyone everywhere.
