Abstract :
New relationship between Adjacent Channel Power Ratio (ACPR) to the 1dB compression point (PLI), third order intercept point (IP3) and the difference in dB between those values is presented. To get this, it´s necessary to find a formula to estimate the non-linearity of the amplifier using a fifth order Taylor series. The coefficients´ Taylor series are related to the linear gain and to the difference between the third-order intercept point and the 1dB compression point.
