This thesis describes the design of two particular types of conventional distributed amplifiers and treats a proposed split-band amplifier. The method used for the conventional designs is an iterative synthesis process developed at Stanford University in 1952. The objective was to investigate the possibility of producing distributed amplifiers of superior performance. Only amplifiers with a flat amplitude response were considered since the calculating equipment available was inadequate for the computations involved in producing amplifiers with other types of response characteristics. Three designs of one form of conventional distributed amplifier were carried out. These were amplifiers with ladder networks for delay lines and with both delay lines identical except for a possible difference in impedance level. None of the three amplifiers had theoretical characteristics which justified an attempt to construct them. The other conventional amplifier was one employing ladder-like networks for the delay lines with each of the lines symmetrical about the mid-point of its length and with both lines identical except for a possible difference in impedance level. An attempt to design one of these amplifiers produced new information beyond that reported in the original work at Stanford University. Furthermore, when using the iterative technique to design this amplifier, there seemed to be reasonable doubt as to whether or not the process was always convergent. No definite opinion on the matter was formulated since it would have required that the calculations be continued through more cycles of iteration than could reasonably be carried out with the computing equipment at hand. Finally, a proposed split-band amplifier was investigated and its theoretical gain-bandwidth characteristics were compared with those of a conventional distributed amplifier. It showed a slight advantage, but this was far outweighed by certain serious inherent disadvantages and the project was discontinued. The investigation has shown that it is impractical to carry out the calculations involved in the iterative prodecure when using a hand calculator. Also, some doubt as to the general convergence of the iterative synthesis process has been raised. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Graduate
