BEAM-TYPE PARAMETRIC AMPLIFIER
Abstract
The Kompfner dip experiment using 2 couplers was performed, and the result verified the theoretical Kompfner dip length, beam-to-circuit synchronization, and theoretical power-transfer equation. The effects of axial beam velocity spread by controlling the cathode magnetic-flux linkage were investigated for signal transmission and signal transfer. The narrowband characteristics of the Kompfner dip as a function of frequency is discussed, and the possible solution is shown. A low-frequency oscillation at synchronous voltage to the in-phase mode was observed; good termination at one end of the coupler is the solution to the problem. The experimental result of a pump-circuit study is presented. A pump circuit was designed for a specified gain. (Author)
