摘要: The present invention relates to an arrangement and a method for amplifying high frequency RF signals having amplitude phase variations. objective problem of the is provide efficient power amplifier signals. object achieved by introducing Signal Conditioning Device (SCD) that converts baseband SI SQ into tri-states STI, STQ. STQ are time multiplexed, which results in single can be used amplify signal on In-phase (I) channel Quadrature (Q) channel. Hence, does not require combiner.
