This paper presents the development of power MMICs in GaN HEMT technology for X-Band T/R modules. We will focus here specifically on the transmit path, which contains the high power amplifier and its power driver. A step by step description of the tasks in order to design this channel will be done, beginning from a short overview of the epitaxial process to the presentation of its measured and simulated...
This paper considers a new approach for nonlinear system level models dedicated to high RF power amplifiers. The constant increase of power density imposes to take into account of thermal effects. In this framework, a new electro-thermal behavioral model based on the coupling between a behavioral electrical model and a thermal reduced model predicting the operating temperature of the amplifier is...
System-level models simplify the analysis of complex RF systems, such as transmission-reception modules, by expressing global input-output relationships. However, the development of high RF power models for nonlinear subsystems requires the prediction of the distortion induced by low-frequency memory effects such as self-heating effects. In this framework, we present a new electrothermal behavioral...
