At the core of Alaris Kuhne’s LNC design is a focus on minimising system noise temperature and preserving carrier-to-noise ratio (C/N). This is achieved through ultra-low noise amplifiers, carefully optimised local oscillators, and high-selectivity filtering. The result is enhanced link margin, allowing broadcasters to operate reliably even in challenging conditions such as long-distance transmission paths or adverse weather environments.
Key Features and Benefits
· Ultra-low noise figure for improved signal sensitivity and superior C/N performance
· High gain with excellent flatness, ensuring consistent signal levels across the band
· Exceptional frequency stability, supporting accurate demodulation and reducing signal drift
· Advanced filtering to minimise out-of-band interference and signal distortion
· Wideband and application-specific frequency coverage for broadcast flexibility
· Robust IP67-rated enclosure, providing complete protection against dust and water ingress
· Proven resilience in extreme environments, including installation on high sea masts
· Compact, lightweight design for easy integration into fixed and mobile broadcast systems
· High reliability, reducing maintenance requirements and operational downtime
Proven in Global Broadcast Events
Alaris Kuhne LNCs have been approved and deployed in some of the world’s most demanding broadcast scenarios. These include large-scale international events such as the FIFA Women’s World Cup in Australia, Olympics 2024, high-speed global coverage of Formula One races, and the complex, multi-stage broadcasting of the Tour de France.
Such events place significant technical demands on broadcast infrastructure, requiring stable frequency performance, low phase noise, and uninterrupted signal acquisition across diverse and often harsh environments. Alaris Kuhne LNCs have consistently demonstrated their ability to meet these requirements, ensuring reliable signal delivery to global audiences.
Engineered for Harsh Environments
Broadcast infrastructure is not always deployed in controlled conditions. In maritime applications, for example, LNCs are often mounted on high sea masts where exposure to salt, moisture, and temperature variations is unavoidable. Thanks to their IP67 classification, Alaris Kuhne LNCs are fully sealed against environmental ingress, ensuring dependable operation even in these extreme conditions.
Examples of products in this range are:
