High Linearity 5.2 GHz Power Amplifier MMIC Using the Linearizer Circuit

摘要：

This paper aimed to study the linearity in the 5.2GHz power amplifier microwave monolithic integrated circuit(MMIC),which was performed with a 0.15 μmAlGaAs/InGaAs D-mode pHEMT technology.The poweramplifier (PA) was studied taking into account the linearizercircuit and the eoplanar waveguide (CPW).Based on thosetechnologies,the power amplifier obtained the output power of13.3 dBm and the power gain of more than 15 dB.The inputthird-order intercept point (IIP3) of 1.4 dBm and the outputthird-order intercept point (OIP3) of 22.5 dBm and poweradded efficiency (PAE) of 21％ were attained,respectively.Finally,the overall power characterization exhibited high gainand linearity,which illustrated that power amplifier had thecircuit compact size and exhibited favorable RF characteristics.
