Miniature TWTs were first developed in and in 1980 the first Micro TWT was introduced. These products support 2-37 GHz bandwidth applications.
Abstract: A method for operating a traveling - wave tube module of a operating with miniature helical slow wave circuits manufactured using micro fabrication .. and phased to produce constructive but unequal interference on the two plates....
Product miniature micro traveling wave tubes traveling fastThe system also includes a voltage probe connected between the power supply input and the signal input, wherein the probe injects a compensating signal into the signal input to compensate for variations in an output signal of the power supply over time. A series of overmoded cavities are bounded by parallel or concentric grids that may be separated by metallic spacers adapted to function as a photonic bandgap circuit to suppress competing electromagnetic modes. Abstract: For a traveling-wave valve arrangement with a traveling-wave valve and a linearizing circuit arrangement, it is proposed to design the linearizing circuit arrangement and the traveling-wave valve as one constructional unit and, for the thermal protection of the linearizing circuit arrangement in the simultaneous presence of a high permissible temperature of the valve housing, to maintain the circuit arrangement by means of an active cooling element at a nondamaging temperature lower than the one of the wall of the valve or of a common wall.

Abstract: An amplifier system is disclosed. The switch connects the helix electrode and the anode electrode through the voltage-limiting circuit, or causes a short circuit between the helix electrode and the anode electrode. Method for the sublimation or pyrolysis of hydrocarbons using RF energy to break covalent bonds. Alain Durand, Alain Le Clair. Each one of the plurality of collector electrodes has a distinct voltage level applied thereto defining a decelerating electric field within the collector. System and method for noise and spurious suppression in power amplifier systems.
