MICROWAVE TUNNEL DIODE MIXER-AMPLIFIER.
Abstract
The theoretical performance of an idealized equivalent mixer circuit, with short-circuited image impedance and positive output impedance, is characterized by expressions for conversion gain, mixer noise figure, system noise figure, input and output impedance, and the signal source impedance required for minimum noise figure. The results of a typical numerical computation of these quantities are displayed graphically as a function of the local oscillator amplitude, with the bias fixed slightly below the peak voltage, in the positive conductance region. The experimental program has begun with tests of the i. f. portion of the mixer. (Author)
