Characteristics Modeling of GaN Class-AB Dual-Band PA Under Different Temperature and Humidity Conditions

As the technology scales down, besides CAD tools and design guidelines, understanding circuit performance degradation as a consequence of transistor becomes essential for designers. Due to several adverse environmental conditions, study in power amplifier (PA) is very demanding research. In this paper, an RF PA experimentally studied observe various characteristic degradations broad range operating temperature humidity conditions. Based on few key measurement points, measurement-based modeling method proposed help designers make intelligent decisions minimize effects. This uses four two-dimensional interpolation models, results show that prediction planar models are good agreement with results. The presented article select can analyze parameters advance. Cubic spline has highest model accuracy among while nearest offers shortest training time.
