Thales contributes to new and exciting applications in the fields of HDTV, Navigation, Internet, Science, Telecommunications and Broadcast. Thales has heavily invested in its production sites in order to anticipate the demand for growing communications needs.

With our customers' support, it is our goal to continue to supply the satellite community with proven TWT-based solutions. Thales is committed to growing our cooperative relationships with our customers as we explore new technologies and solutions for the next generation of satellite applications.

Traveling Wave Tubes (TWTAs) for Space applications

• L-band - Thales' TWT have already been selected for several satellite navigation systems worldwide, including Giove A, the first demonstrator for Europe's planned Galileo system, launched in December 2005. Tubes in our TL 1099 family develop up to 250W of power.
  
  
• S-band - Applications using this frequency, such as satellite radio or mobile TV, require very high transmission power. TWTs from the TL 21019 family have naturally been selected for recent programs, since they develop 100W to 275W of power, and offer performance that perfectly matches all user needs.
  
  
• C-band - The favorite frequency band for data transmission and video broadcasting services in certain parts of the world.
   Thales' TL 4099 C-band TWTs deliver from 70W to 125W of power, and have logged over 60 million hours of operation in orbit. 
  
  
• X-band - Thales' X-band TWTs set the standard for a number of different scientific and observation missions, as well as secure data transmission. The TH 4604, TH 4704 and TH 4300 families deliver the best performance on the market, over a power range from 15W to 160W.
  
  
• Ku-band - The standard of reference for data transmission and video broadcasting. Thales' Ku-band TWTs offer an unrivaled legacy, with more than 5,000 tubes in orbit, totaling over 220 million hours of operation. The TL 12099, TH 4725 and TH 4825 families cover the power range from 20W to 220W to meet the full spectrum of user requirements, with bandwidth up to 2.05 GHz.
  
  
• Ka-band - News applications for  this frequency demand enhanced performance over the full bandwidth.
  Ka-band TWTs by Thales rise to the occasion, with the TL 20099 and TH 3990 families offering 50W to 130W of power, soon to be extended to 170W. To meet growing demand, Thales has made significant investments to boost its production capacity in this band.
  
  

Traveling Wave Tubes Amplifiers (TWTAs) for Satellite uplinks applications:

Thales makes ground station TWTs that perfectly match market requirements. For instance, our conduction-cooled C-band, Ku-band and DBS-band TWTs set the standard in this market. Our recently introduced family of Ka-band mini-tubes opens new horizons for both civil and military applications, since they can be used in lightweight, compact yet powerful transmitters. The TH 4080 already in operation can deliver 50W of linear power.
