Sažetak
An efficient and sufficiently general method of microwave mixer analysis is presented. The process involves first analyzing the nonlinear device under large-signal excitation only. by the use of nonlinear analysis the LO voltage waveform is obtained, and diode differential conductance and capacitance are determined. A linear diode model, and conversion admittance are formed which relate the small-signal sideband currents and voltages of the diode. The expression for conversion loss and port impedance are determined. A computer program is developed to perform the analysis. results are presented to show how the reactive terminating impedances at image and sum frequency ports affect mixer input and output impedances, and mixer conversion loss.
