One way analysis of variance for parameter S of isolator and regression analysis to the correlation between parameter S and ACPR

Abstract

In the design of the single board of mobile communication, isolator is often used in between the amplifier stage and the drive stage to enhance the interaction between circuits and to improve the adjacent channel power ratio (ACPR) of power amplifier channel and other wireless performance indexes. In this paper, the one way analysis of variance (ANOVA) was used to study whether there is indicator difference in single board when using different isolatorfirstly. Then, the regression analysis method was employed to verify the correlation between $y$ (ACPR of the single board of radio frequency power amplifier) and $x$ (parameters S11 or S12 of isolator). Finally, it concluded that the ACPR values may be affected by different types of isolators, and there is no significant univariate linear fitting relationship between the parameters S11/S12 of isolators and the ACPR of single boards.
