Исследование уплотнения спектра сигнала в нелинейных структурах квазистационарным методом

Радиотехника и электроника. 2014. Т. 59. № 9. С. 864-871.
Андреевская Т. М., Солнцев В. А.

The transmission of а complex signal through nonlinear structures (semiconductor diodes, high-power transistor amplifiers, microwave vacuum amplifiers, ets.) is investigated by means of quasi-stationary method, and functional models of devices are applied. The  models  use  the  quasi-stationary method of  analysis of multifrequency signal transformation. Certain  properties and peculiarities  that  are exhibited by  nonlinear devices  and that induce  so-called  spectrum multiplexing, i.e., formation of combination components,  including those observed within the basic spectrum,  are considered. The possibilities  of spectrum multiplexing in nonlinear elements  with a polynomial quadratic, cubic, or more complicated  characteristic  are discussed.
