Patent ID: 8406711

Claim:
A method of power amplification, comprising: receiving information; receiving a frequency reference signal in accordance with a desired output signal frequency; determining a complex envelope from said received information; determining a phase shift angle using said complex envelope, wherein said phase shift angle is equal to a phase difference between first and second substantially constant envelope signals; using said phase shift angle to generate in-phase and quadrature phase amplitude control signals; controlling a phase angle of said frequency reference signal to generate a phase angle controlled frequency reference signal of equal phase as a desired output signal; generating said first and second substantially constant envelope signals using said in-phase and quadrature phase amplitude control signals and said phase angle controlled frequency reference signal; providing said first and second substantially constant envelope signals to a MISO (multiple input single output) amplifier comprising two or more circuit branches each comprising one or more transistors, wherein said first and second substantially constant envelope signals are amplified and combined to create said desired output signal using said MISO amplifier.
