Abstract:
    The disclosed method for increasing RF power amplifier linearity comprises: base band acquires output power of current RF power amplifier from received top signaling to determine the size of IQ signal for RF transmitter; the base band sends IQ signal to target, and the latter processes gain or received IQ signal to send signal to a RF power amplifier. This invention can ensure the output signal linearity so as well as the RF power amplifier.
