  • Very high efficiency flexible travelling wave amplifier
    Patent number: 8742840
    Abstract: A travelling wave tube amplifier includes: a travelling wave tube comprising a cathode, a helix, an RF input, an RF output, and a plurality of collectors, and an electronic power conditioner providing power supply and electrode polarization to said travelling wave tube, wherein said electronic power conditioner comprises flexibility control means allowing to adjust, via control commands sent through a databus, the helix to cathode voltage and the collector voltages.
    Type: Grant
    Filed: October 20, 2011
    Date of Patent: June 3, 2014
    Assignee: Thales
    Inventors: Etienne Cuignet, Philippe Fayt, Emile Tonello
  • Power management system for dual travelling wave tube amplifier
    Patent number: 8674759
    Abstract: A power management system, notably for a dual travelling wave tube amplifier, includes: two travelling wave tubes, each comprising one Anode Zero electrode, and an electronic power conditioner, the power management system being implemented in said electronic power conditioner and including power management means associated with each travelling wave tube, configured for setting the Anode Zero electrode voltage to a determined minimum value when a sleep mode is activated, the power management means maintaining the travelling wave tube operating power at a value below its nominal working range. A sleep mode can advantageously be combined with an RF-Mute mode.
