Abstract

Abstract

Based on the results of the theoretical analyses and simulations, the relationship between the Gaussian pulse parameters (pulse width, pulse amplitude, pulse repetition frequency) and the interference effects on a low noise amplifier (LNA) is discussed. The experiments are carried out on the LNA operating at the 40-80 MHz band to confirm the interference effects. The results show that: the interference characteristics are much depended on the operating band of a LNA and the pulse parameters; the pulse amplitude is the most significant factor among all the pulse parameters; the increase of the values of the above three pulse parameters will enhance the interference effects.
