Thales' Dual-TWT technology brings a new dimension to satellite communications. Drawing Thales’ unrivalled expertise in Travelling Wave Tubes, this solution simultaneously amplifies two signals within a compact and lightweight design. It delivers exceptional high-capacity transmission, exceeding the evolving demands of both current and next-generation flexible satellites.

STRENGTHS

Compact and lightweight design

Arranged in a matrix configuration within a compact architecture, Dual-TWT has been configured to offer a reduced size and low mass while maintaining high performances.
High Efficiency

Engineered to maximize efficiency, the Dual-TWT delivers superior output power across a wide frequency range, ensuring optimal signal quality and reliability.
Dual Chanel Amplification

The Dual-TWT enables simultaneous amplification of two signals, significantly enhancing system efficiency and reducing hardware complexity by integrating multiple functions into a single device.

Leveraging the synergies between telecom and space tube technologies, Thales Dual-TWT combine the best characteristics of both domains to deliver an innovative, high-performance solution capable of simultaneously amplifying two independent signals. Ideal for applications requiring reliability, flexibility and robust amplification (Software Defined Satellites). Dual-TWT ensures optimal signal integrity and enhanced operational efficiency, making them the preferred choice for modern telecommunications and space missions.

With over 1.8 billion cumulated hours of operation in orbit, our vacuum tube technology has powered some of the most renowned space missions. Trusted by industry leaders such as Thales Alenia Space's SPACE INSPIRE and Airbus Defense and Space's ONESAT, our solutions are critical to their mission success.

FEATURES

Active antennas, which integrate amplifiers directly within the antenna structure, enable precise beam control and optimized coverage while reducing the satellite's footprint. Dual-TWT devices, by simultaneously amplifying two distinct signals, provide the agility crucial for modern communication satellites. Their performance (including bandwidth and power flexibility), combined with compactness and high electrical efficiency, perfectly complements new telecommunications systems.

Dual-TWT is well-suited to the demanding conditions of the space environment, including thermal variations, radiation, and other mechanical constraints. Unlike Solid-State Power Amplifiers (SSPA), TWT devices offer superior electrical efficiency, enabling advantageous thermal management. Thus, they outperform other available amplification solutions, boasting longevity and durability inherited from classic tube technology.
