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 EBPAs 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.
