THEORY AND DESIGN OF FREQUENCY CONVERTERS USING COMBINATIONS OF PARAMETRIC ELEMENTS.
Abstract
This dissertation treats the theory, gain-bandwidth limitations and optimum design of frequency converters comprised of both reactive and resistive nonlinear elements. These combinations exhibit a number of interesting and useful properties not found in circuits with only a single type of nonlinear element. When the resistive and reactive nonlinear elements are pumped in time-quadrature, the forward gain is maximized while the reverse gain and noise figure are minimized. Lower-frequency pumping is found possible with first order nonlinearities. The nonlinear RC, RL and RLC converters have respectively what is termed second, fourth and sixth order types of input-output isolation. The fundamental gain and bandwidth limitations of the converters are discussed in detail. The non p.r. converter admittances are approximated by a linear RLC network which incorporates their frequency dependence over the passband. The theory of broadband matching is then utilized to yield the fundamental gain-bandwidth limitations. (Author)
