Popis:	Simplified relationship between the intermodulation distortion ratio (IM3) on two tone test and the ACPR in CDMA signal test is derived. Due to better linearity (decreased intermodulation distortion and IMD null) at high power level in class AB amplifier, enhanced ACPR performance is achieved at high power input. The comparison between the measured ACPR and the calculated ACPR from two tone test shows that they are in good agreement.
