Abstract :
This contribution describes the design of an ultra wide band hybrid power amplifier for applications in the frequency range from 1 GHz to 6 GHz. The amplifier is designed with a GaN-on-Si HEMT device provided by SELEX-SI, in a single ended configuration and using the source/load-pull and Scattering parameters measured data. The amplifier has been designed using a CAD oriented broad band matching approach for both input and output networks. From 1 GHz to 6 GHz, the expected output power at 3dB of gain compression is around 41 dBm.
