Telecommunications work like a relay race. A signal transmitted by the ground is picked up by the satellite’s receiver antenna, filtered, its frequency changed and amplified, and then passed through a network of transmission antennas before being routed back down to Earth.
 
�׻���������’ traveling wave tubes (TWTs) and amplifiers are behind this relay race. Today, with over 18,357 �׻��������� TWTs launched into orbit since 1974 and 900 million hours of operation, the technology supports the majority of global communication uplinks.
 

“Most data sent by satellites uses a �׻��������� amplifier,” Jean-François Auboin, Space Programs Director at �׻���������, says, “and the utility is huge.”

�׻��������� today sets the global standard for civil and military data transmission. Applications include space-based HDTV and radio broadcasting, data transmission, telecommunications, internet, in-flight connectivity, observation and navigation.

“We are adapting to a big shift in the space market,” Jean-François Auboin shares. “We are improving our performance in bandwidth, linearity, efficiency and reliability.”

He acknowledges that �׻��������� do so as a company that is already seen as a reference in the market.

Over the past years, �׻��������� has built-up an unmatched expertise in Traveling Wave Tubes technology for both Satcom downlinks and uplinks. We today rely on these power amplification solutions in satellites to keep us safe and connected.
