Abstract :
In this paper, we analyze the nonlinear effect of an RF power amplifier on CDMA signals and then derive the design formulas which provide the direct relation between the power transistor´s traditional nonlinearity parameter, the 3rd order intercept point (IP3) and the out-of-band emission levels for CDMA signals. This result will be very useful to system and component engineers in design of RF power amplifiers for CDMA wireless systems.
