Research is concerned with the development of a straight through low noise amplifier, electronically tunable from 4000 to 6000 kmc. Pertinent literature is reviewed and a theoretical foundation for subsequent experimental and theoretical work established. Upper bounds for practically realizable signal, idler, and pump bandwidths are determined. It is shown that even with an infinite number of tuned sections, the bandwidth of each circuit is ultimately limited by the electrical characteristics and parasitic elements of the varactor diode. Noise Figure limitations with presently available diodes are reviewed and the proper pump frequency is approximately determined. Author
