J. Whelehan · Defense Technical Information Center (DTIC) · 1962
Abstract : Work was continued on the design, development, and fabrication of tunable C-band reactance amplifiers. The amplitude and phase stability of a tunable C-band reactance amplifier as a function of pump power and frequency is discussed. The effect of the circulator bandwidth on the stability of the amplifier is analyzed. The importance of an efficient broad-band pump circuit is emphasized, and the tunability of the amplifier is computed and shown in graphical form. The availability of suitable varactor diodes is also discussed. (Author)
