Abstract

This paper aimed to study the linearity in the 5.2 GHz power amplifier microwave monolithic integrated circuit (MMIC), which was performed with a 0.15 μrn AlGaAsZInGaAs D-mode pHEMT technology. The power amplifier (PA) was studied taking into account the linearizer circuit and the coplanar waveguide (CPW). Based on those technologies, the power amplifier obtained the output power of 13.3 dBm and the power gain of more than 15 dB. The input third-order intercept point (IIP3) of 1.4 dBm and the output third-order intercept point (OIP3) of 22.5 dBm and power added efficiency (PAE) of 21 % were attained, respectively. Finally, the overall power characterization exhibited high gain and linearity, which illustrated that power amplifier had the circuit compact size and exhibited favorable RF characteristics.
