1. A dualband phone having dualband amplifier control using a single power amplifier controller, comprising:

  • a first power amplifier for amplifying the power of a signal transmitted at a first frequency band;

    a second power amplifier for amplifying the power of a signal transmitted at a second frequency band;

    a power amplifier controller for controlling the amount of amplification performed by one of said first and second power amplifier;

    a single switch connected to said power amplifier controller for switching the connection of said power amplifier controller between said first and second power amplifier; and

    a processing means for monitoring the quality and strength of a received signal from a base station and instructing said switch to switch its connection between said first and second power amplifier based upon a determination of which of said first and second frequency bands provides an optimal balance between signal quality and signal strength.
