Multimode Phased Array Tube

Abstract

This contract was for the test and evaluation of the tetrode type 8590/4CPX250K for long pulse and high duty factor service in phased array applications. The limits of the tube were determined. Also, a new tetrode with the same size and outline of the 8590 was developed to provide pulse lengths to 10ms with a duty factor to 0.03. The new tetrode uses a CPC (coated powder cathode) and a new anode cooler design to permit an anode dissipation of 500 watts. An rf cavity to work with the new tetrode was developed to operate at 435 MHz with 10kw output power. A bandwidth of 30 MHz to the -1dB points was attained using overcoupled circuits. The power gain of the tube and cavity combination was over 10dB.
