Harnessing the power of mmWave frequencies

Beginning with the K/Ka-band, which is the first widely adopted mmWave band used extensively across satellite communications systems. mmWave frequencies offer substantially higher throughput than lower-frequency alternatives, enabling higher-data-rate satellite links and supporting advanced communication architectures. As a result, the Ka-band is a foundational enabler of high-capacity data transmission and next-generation network performance.

Given its broad adoption, the Ka-band ecosystem is mature, with a well-established supply chain and semiconductor technologies capable of delivering high power density. At Filtronic, we are advancing the state of the art by integrating these semiconductor devices with our proprietary ultra-low-loss waveguide combining IP. This approach allows us to develop solutions that effectively compete with incumbent travelling wave tube amplifiers while delivering a range of performance and reliability advantages.

Moving to Q-band, this frequency range enables a new class of high-resolution radar and advanced imaging systems. Its propagation characteristics allow for exceptional precision, fine spatial resolution, and enhanced target discrimination, making it highly attractive for next-generation sensing and surveillance architectures.

Q- and V-band are also emerging as the next logical evolution for satellite communications. Building on the widespread adoption of Ka-band, these higher-frequency bands offer substantially greater available bandwidth, enabling significantly higher data throughput and supporting ultra-high-capacity wireless links. This makes Q/V-band attractive for forward-leaning Satcom operators seeking to move beyond the constraints of Ka-band to achieve superior spectral efficiency and network performance.

At Filtronic, we are capitalising on this momentum developing a range of SSPAs, LNB, BUC and BUC-Amplifiers with leading edge performance.

Advancing further up the frequency spectrum, E-band provides access to significantly wider contiguous bandwidths, making it a critical enabler for ultra-high-capacity communication systems. Historically adopted for point-to-point wireless links, E-band has become a cornerstone of modern backhaul and XHaul networks, particularly within 5G and emerging next-generation telecom architectures. Its ability to support fibre-equivalent data rates over wireless links has driven widespread commercial adoption. As a result, the E-band supply chain is highly mature, with a robust ecosystem spanning semiconductor technologies, RF components, and system integrators. This maturity has accelerated its migration from terrestrial telecoms into advanced Satcom and high-performance defence communication systems.

Filtronic has been at the forefront of E-band innovation for more than a decade. By integrating industry-leading semiconductor devices with our proprietary ultra-low-loss waveguide combining technology, we have achieved market-leading output power levels suited for the next generation of satellite communication networks. This capability was validated in 2024 when we announced a strategic partnership with SpaceX for the supply of E-band amplifiers supporting the Starlink ground segment, reflecting both the technical strength and industrial scalability of our solutions.

Our first-generation designs utilised GaAs technology. With the recent introduction of smaller-gate-length GaN processes, Filtronic is now developing a new GaN-based amplifier module aimed at delivering approximately three times the output power of prior generations. This step change will further strengthen our competitive position in high-power E-band subsystems.

Operating between 92 and 114 GHz, W-Band is opening new frontiers in high-frequency communications, sensing and imaging. The large bandwidths available at these frequencies enable ultra-high data rates, while the short wavelengths support exceptional precision in radar, Earth observation and advanced sensing applications.

As demand grows for greater capacity, higher resolution and more capable RF systems, W-Band is attracting increasing attention across the space, defence and scientific sectors. From next-generation satellite communications and inter-satellite links to high-resolution radar and remote sensing, W-Band offers the performance needed to support the most demanding emerging applications.

Filtronic is investing in advanced W-Band technologies to help accelerate the adoption of next-generation mmWave systems. Combining expertise in high-frequency RF design, semiconductor integration, packaging and advanced manufacturing, we develop subsystem solutions that deliver the precision, reliability and performance required for deployment in challenging operational environments.

Building on decades of experience in RF, microwave and mmWave technologies, we are helping customers explore new opportunities at W-Band and unlock the potential of low latency, high bandwidth connectivity.
