抜粋

A novel linearization technique which improves the phase distortion and gain compression of a power amplifier is proposed in this paper. Moreover, a low distortion and high efficiency AlGaAs/GaAs HBT MMIC power amplifier for the 1.9 GHz PHS system has been demonstrated using the novel linearization technique. The HBT MMIC power amplifier exhibits an output power of 21 dBm and a power added efficiency as high as 37% at an operation voltage of 2.7 V with linearity well within the PHS standard.
