초록

In order to predict the effect of power amplifier non-linearity for digital modulated signal, this paper analyses the adjacent channel power ratio(ACPR) with the various AM-to-PM distortion levels. As the phase distortion increases from 0$^{\circ}$ to 12$^{\circ}$ at 1㏈compression point by 2.4$^{\circ}$ step, the input power level which satisfies the required ACPR decreases from 3.5㏈ to 6.5㏈ less than the 1㏈ compression input power.
