With mobile phones being used More and more widespread, it required that the standby time of phones should lasted longer and longer. There are two ways to extend the standby time. Firstly, increase the capacity of the battery. And secondly, reduce the power consumption of the mobile phone. The RF module's power consumption accounts for a large part of the mobile phone. So the Low power RF modules are on more and more attention by everyone. The method fol owed would provide an improved method to reduce the power consumption of the power amplifier of the second generation mobile phone.
