GaN and GaAs deliver RF for Internet of satellites


Qorvo amplifiers are being used in the telemetry tracking and control modules developed by Syrlinks for Airbus OneWeb satellites

Qorvo has announced that its amplifiers are being used in the telemetry tracking and control modules developed by Syrlinks for Low Earth Orbit (LEO) satellites. The first six satellites of the constellation, designed by Airbus OneWeb Satellites, were recently launched to provide internet connectivity practically anywhere in the world. The industry-leading reliability and performance of the Qorvo products reduce stress on the satellite power systems and ensure signal integrity in both transmit and receive modes.

Close collaboration and flexibility across both companies˙ functional teams were key to the success of this project. Syrlinks integrated the Qorvo RF front-end components into the space-qualified module and provided product definition and performance requirements for the Qorvo products. Qorvo provided product application, manufacturing and test support.

The MMIC power amplifier selected is built on Qorvo˙s 0.15µm GaN process, QGaN15, which supports high-frequency applications through 40GHz. The Low Noise Amplifier is built on Qorvo˙s 90nm GaAs pHEMT process, QPHT09, which is said to have best-in-class noise figure. Qorvo has nearly 100 commercial products (die and package options) built on these processes.

Guy Richard, Syrlinks˙ CEO, said: "Syrlinks has been investing for three years in the NewSpace approach associated with the latest generation of components. These efforts required stronger links with manufacturers of high-performance and innovative components, such as Qorvo. We are always looking for the best in terms of performance and reliability."

Roger Hall, general manager, Qorvo High Performance Solutions, said: "Qorvo˙s commercially-packaged products are proving their operational readiness to meet the harsh environment of space. By combining powerful process technology with advances in packaging, Qorvo is enabling high power devices that also achieve high reliability and are operationally rugged."

Syrlinks specialises in radio communication and geolocation subsystems for space, defense and safety applications. Its NewSpace products perfectly meet the new requirements of the space industry. Syrlinks˙ telemetry, tracking and control modules enable remote sensing and monitoring of the Airbus OneWeb LEO satellites for internet connectivity service.
