This paper presents a Power Amplifier (PA) for IEEE802.11p applications. The design process, simulation results and practical results are presented. The use of suitable matching networks to prevent instability as well as gain and power output improvements is described. The PA was simulated and designed using Advanced Design System (ADS) by Keysight Technologies. The implementation was tested using an IEEE802.11p signal from a Signal Generator. It meets the linearity requirement for a wide range of output levels, meaning that it can be used in three of the four power classes of the IEEE802.11p standard. The proposed design may be improved using some kind of compensation such as Digital Pre-Distortion, especially to be compliant with the D class.
