Abstract : The development and design of a broadband, lownoise microwave amplifier using ceramic triodes is presented. After the feasibility of ceramic triodes in microwave amplifiers was proven by initial experiments with single-stage and twostage amplifiers, a four-stage broadband amplifier with approximately 33 db gain was designed. Experiments were made using the General Electric Z-2869 and 7768 ceramic triodes; the Z-2869 gave better results and was used in the final fourstage amplifier. Bandwidth was measured at the 1 db points. Noise figure was 11.5 db or better across the band and maximum gain variation across the band was 0.7 db. No phase measurements were taken; however, phase characteristics of this amplifier are being investigated in conjunction with another project. (Author)
