ABSTRACT:
A CDMA system is provided which includes a power amplifier module have a DC current amplifier. The DC and current amplifier detects a DC component of an input signal and amplifies this detected DC component. The power amplifier module also includes an amplifier which receives the current amplified by the DC current amplifier as an input current. The input signal supplied to the DC current amplifier changes in response to an input power level.
