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
