The high gain, high power density, and reasonably high terminal impedances that are available with “high band gap” devices such as SiC and GaN HEMTs have provided some powerful tools to the PA designer’s “bag of tricks”, but there are still a few landmines that need to be considered early in the design process to insure a robust solution when designing a high power broadband amplifier. One that designers often step on is device stability (or more appropriately, instability). This application note will discuss the fundamental cause of this instability, and practical methods to mitigate the problem in a real world environment. |
