5 KW, CW Low Loss Booster Tube for Military SATCOM Systems.

Abstract

The report documents the development of a low loss single section coupled cavity traveling wave tube designated as a Booster Tube which may be used in military satellite communication ground terminals. The primary objective of the program was to design, fabricate and test a prototype tube which would deliver 5 kW of CW power in the frequency band of 7.9 -8.4 GHZ with 10 dB of saturated gain and low insertion loss. The first task on the program was the modification of a design previously tested at a higher power level and the analytical optimization of this design. This was followed by the fabrication of test circuits for cold rf testing. An electron gun was designed with a modulating anode and tested in the beam analyzer. These tasks then led to the design and construction of a prototype tube. The tube was tested using a high power klystron as a driver. The klystron was tuned in 100 MHz steps across the band and the power, gain, amplitude phase and stability were measured. These data are presented in the contents of this report.
