“…Using perturbation methods, it is possible to analyse a nonlinear circuit in terms of a number of equations, each corresponding to the harmonic modulation product present [6][7][8][9]. An alternative method to the classical frequency-domain analysis of mixers has recently been suggested [10][11][12], using a time-domain approach to obtain the scattering matrix of the complete mixer.…”

The main objective of the paper is to present in one place all the performance curves for the various modes of operation of the resistive lattice H mixer. Four distinct cases arc considered; two narrowband mixers with open-and short-circuit terminations at the image frequency, and two broadband circuits with matched and mismatched conditions at the RF port. The design formulas are tabulated, and the expected minimum conversion power loss, as well as the optimum terminations required over a wide range of operational levels, are plotted for each type of mixer.

This paper gives a mathematical analysis of a heterodyne conversion transducer in which the nonlinear element is made up of a nonlinear resistor and a nonlinear capacitor in parallel. Curves are given showing the change in admittance and gain as the characteristics of the nonlinear elements are varied. The case where a conjugate match exists at the terminals is treated. It is shown that when the output frequency is greater than the input frequency, modulators having substantial gain and bandwidth are possible, but when the output frequency is less than the input frequency, the converter loss is greater than unity and is little affected by the nonlinear capacitor. The conditions under which a conjugate match is possible are specified and it is concluded that a nonlinear capacitor alone is the preferred element for modulators and that a nonlinear resistor alone gives the best performance in converters.

This paper discusses certain important aspects of the noise behavior of a pumped resistive diode containing shot and thermal noise sources. The derivation of the following result has a central role in the discussion. It is shown that the noise behavior of a pumped diode which does not contain 1/f noise sources can be derived in a very simple way from Nyquist's theorem. This follows from the fact that the small‐signal terminal behavior of such a diode can always be represented, in the frequency range of practical interest, by means of a connection of two linear and time‐invariant networks of which one is noiseless and the other is dissipative, contains only thermal noise sources and is held at a uniform temperature.
