摘要

PURPOSE: An apparatus for improving the efficiency of a Doherty power amplifier is provided to supply a drain voltage of a main amplifier to a high voltage and a low voltage according to a preset reference voltage by detecting the envelop of input signals.;CONSTITUTION: A main amplifier(101) amplifies a basic signal of input signals. A peaking amplifier(102) amplifies peak signals. A first transformer(103) is connected to each output terminal of the peaking amplifier and the main amplifier to perform load modulation. A second transformer(104) is connected to the peaking amplifier and the first transformer to change loads. A dynamic bias switching part(200) detects the envelop of the input signals.;COPYRIGHT KIPO 2012
