摘要
The guidelines for designing a high efficiency and low distortion 2-stages Gallium Nitride (GaN) power amplifier (PA) are presented. In particular, the developed approach to mitigate the phase distortion (AM/PM) without worsening the efficiency and gain features is adopted to design a 7 GHz PA based on 0.25 mu m GaN process from TriQuint. When tested with continuous wave signals the PA shows a saturated output power higher than 37 dBm, with an efficiency larger than 60 % and an AM/AM and AM/PM distortions lower than 2 dB and +/- 1 deg, respectively. The MMIC chip size is 3x3 mm(2).
