Abstract

Abstract

In this paper, the nonlinear characteristics of the amplitude and phase of a single Schottky diode and series and parallel analog pre-distortion circuit are analyzed. The simulation results show that the diode can be used as an adjustable core component of an analog pre-distortion circuit. By using the transmission matrix, it is found that connecting the Schottky diodes in different positions of the predistortion circuit and selecting serial or parallel modes can improve the amplitude and phase compensation curves. The simulation results show that connecting a Schottky diode in series or in parallel at different positions of the circuit can effectively change the position and slope of the curve, so as to obtain an ideal target curve shape.
