The experimental and theoretical results are described of a program to develop and construct low-noise tunnel diode mixers and converters. Studies lead to a conclusion that reasonably low noise figures are possible when the diode is biased near the valley. This allows the tunnel diode converter to be operated with positive input and output conductances which simplifies the stability problem. The possibility of conversion gain with positive terminal conductances is also discussed. Assumptions which limit the accuracy of the theoretical results are pointed out. A separate section is devoted to the theory of measurement techniques and apparatus. Author
