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 7GHz PA based on 0.25 umm 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.

Abstract
The guidelines tor 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 μm GaN process from Tri Quint. 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 AMIPM distortions lower than 2dB and ± 1 deg, respectively. The MMIC chip size is 3x3 mm2.| File | Dimensione | Formato | |
