OPERATIONAL CHARACTERISTICS OF 16 ELECTRON-BEAM PARAMETRIC AMPLIFIERS IN A 900 MCPS PHASE ARRAY
Abstract
The results of an extensive testing program designed to measure the shot-term and long-term operational characteristics of the electronbeam parametric amplifier (EBPA) are presented. Particular emphasis is given to those characteristics which are of interest to designers of phased-array radars. Week-long pump-on amplitude stabilities better than 1 db rms and concurrent pump-on phase stabilities better than 1 degree rms were obtained after certain problems, associated with the EBPA's sensitivity to small changes in magnetic field strength, had been overcome. Other important EBPA characteristics are considered in detail; among these are: double-channel noise figure, gain-phase tracking, phase-frequency tracking, etc. Lift-test data is presented which indicates an EBPA life in excess of 2,500 hours.
