As the use of small, agile drones continues to expand across both civilian and military environments, so too does the need to detect, track, and counter these airborne threats. Modern Counter-Unmanned Aerial System (C-UAS) solutions rely on a blend of sensing, communication, and electronic attack technologies and at the heart of many of these systems lies a crucial component: the RF power amplifier.
Amplifiers at the Core of C-UAS Technology
Power amplifiers play a pivotal role in several aspects of C-UAS operations. They provide the high-power RF energy needed for:
· Electronic attack or jamming, where targeted signals disrupt drone control, navigation, or video links.
· Active detection and direction-finding, using controlled transmissions to locate or track drones.
· Radar-based detection, in systems that actively illuminate airspace to identify small aerial targets.
· Testing and validation, during which amplifiers simulate threat signals or verify jamming effectiveness in controlled environments.
Whether used for transmitting wideband denial signals, narrowband disruption, or radar pulses, a reliable and efficient amplifier is critical to system performance.
Power, Precision, and Protection
Alaris Kuhne amplifiers are engineered to deliver the robust RF output and durability required in demanding defence environments. Their range covers frequencies from a few hundred megahertz up to tens of gigahertz, effectively spanning the bands most commonly used by commercial and hobbyist drones.
Key features that make Alaris Kuhne amplifiers ideal for C-UAS applications include:
· Wide frequency coverage for multi-band operation across common UAS control and telemetry bands (400 MHz to 6 GHz and beyond).
· High linearity, enabling effective engagement of modern, digitally modulated control links.
· Rugged, compact design for mobile or fixed installations in harsh field environments.
· Built-in monitoring and protection, such as VSWR, temperature and power feedback, ensuring safe, reliable operation.
For example, wideband models like the KU PA BB 010600 offer coverage from 100 MHz to 6 GHz for multi-band threat mitigation or testing, while the KU PA BB 070270 delivers up to 80 W across 600–2700 MHz — ideal for higher-power tactical applications. Other units which are used in the C-UAS and C-IED applications, include the KU PA BB 003055 - 100 B and KU PA BB 003350 - 15 B.
Beyond active jamming, Alaris Kuhne amplifiers also enhance system development and validation. Their precision, repeatability, and monitoring features make them valuable for laboratory testing, EMC verification, and field evaluation of counter-drone technologies.
Importantly, all C-UAS operations must be conducted in line with national regulations and defence authorisations. Alaris Kuhne supports system integrators in designing responsible, spectrum-compliant solutions that achieve mission success while maintaining safety and control.
With decades of RF engineering heritage and proven reliability, Alaris Kuhne power amplifiers provide the dependable performance modern defence systems demand. Whether for detection, disruption, or testing, they are a key enabler in protecting airspace and ensuring operational superiority in the evolving drone landscape.
