Fortunately, secure and advanced communications technology is no longer limited to the defence industry; it is also widely used on commercial aircraft. Have you ever wondered what technology makes it possible to stay connected during your flight?
Alaris Linwave is proud to play an important role in enhancing the passenger experience in flight. The company’s high-performance Block Up Converters (BUCs) form a critical part of the satellite communications infrastructure that enables modern in-flight entertainment and passenger Wi-Fi services.
Integrated into leading airborne antenna systems within this SATCOM architecture, our advanced RF modules convert and amplify communication signals for transmission to satellites, helping airlines deliver reliable broadband connectivity, streaming entertainment, and real-time communications to passengers around the world.
One of the most important contributions from Alaris Linwave is its range of Block Up Converters (BUCs).
A BUC converts lower-frequency modulated signals generated by the aircraft's communication equipment into higher-frequency Ku-band or Ka-band signals suitable for transmission to a satellite. It also incorporates amplification and filtering functions to ensure efficient, reliable signal transmission.
Our BUC modules are integrated into manufacturers’ antenna systems used in in-flight entertainment and connectivity solutions on commercial and business aircraft.
Commercial aviation places stringent demands on RF equipment. Alaris Linwave designs its products for airborne environments, focusing on:
Compact size, weight and power (SWaP) efficiency.
Operation at high altitude and across wide temperature ranges.
Compliance with aerospace environmental standards.
High reliability and long operational life.
Integration into certified airborne antenna systems.
Through this specialised technology, we are not only enhancing the passenger experience but also supporting the growing demand for always-connected aircraft across the aerospace sector.
