Brief description of the power measurement of the amplifier a microwave tubes and device for implementing the process

摘要

The invention relates to a method of measurement of the rf power of the output (ps) of a microwave tube amplifier (10), the tube comprising an electron gun providing a beam of electrons, a circuit rf of interaction between a signal rf and the electron beam, the circuit rf having an output of the rf signal amplified, a collector having at least two electrodes to collect the electron beam. The output power rf at the outlet of the rf signal amplified is determined from the measurement of the current ic1 from the first electrode is the closest to the barrel, a calculation of the rf power of the output (ps) being carried out by a predetermined relationship between the current and the output power of the amplificateur.l' invention also relates to a device comprising means for measuring (74) for the implementation of the measuring method according to the invention. Applications: amplifiers microwave tubes, klystrons,.. 1 / p
