WIDE BAND COUPLING DEVICE BETWEEN THE PROGRESSIVE WAVE TUBE DELAY LINE AND THE EXTERNAL TUBE ENERGY TRANSMISSION CIRCUIT, AND PROGRESSIVE WAVE TUBE COMPRISING SUCH A DEVICE

摘要

P BROADBAND COUPLING DEVICE BETWEEN PROGRESSIVE WAVE TUBE DELAY LINE AND EXTERNAL TUBE ENERGY TRANSMISSION CIRCUIT, AND PROGRESSIVE WAVE TUBE HAVING SUCH A DEVICE. / P P The coupling device between the delay line 1 of a progressive wave tube and its waveguide guide 4 having two moldings 40, 41 has a coupling waveguide 3 having a mold 30 ITS EXTREMITES ON LINE 1 AND EXTENDING, ON THE OTHER SIDE, THROUGH ONE OF THE TWO MOULURES OF THE EXIT GUIDE. THE COUPLING GUIDE SECTION 3 INCREASES PROGRESSIVELY, WITH CONSTANT IMPEDANCE, FROM LINE 1 TO THE OUTPUT GUIDE 4 WHILE IT INCLUDES AN IMPEDANCE TRANSFORMER D4 TO ENSURE IMPEDANCE ADAPTATION BETWEEN ITS PART IN A STANDARD GUIDE D5 AND THE COUPLING GUIDE. / P P APPLICATION TO PROGRESSIVE POWER WAVE TUBES. / P
