Digital linear amplification with nonlinear components(linc) transmitter
2008
A digital link transmitter including an inconsistency compensator selecting one or more offset value by monitoring the output signal is provided to compensate the inconsistency between two signal paths of LINC(LInear amplification with Nonlinear Components). An SCS(Signal Component Separator)(110) separates the envelope signal into the first phase data signal and the second phase data signal. A frequency synthesizer(150) produces a plurality of clock signals. One or more digital delay modulator(130, 140) produces a first signal factor having first constant envelop and a second signal component having second constant envelop. One or more non-linear power amplifiers(161,162) amplifies a first signal factor and a second signal factor. One or more non-linear power amplifier produces the amplified second signal component with the respective amplified first signal factor.
