In this paper, application of new technological solution for power switches based on Gallium Nitride (GaN) in Envelope Amplifier for Radio Frequency Power Amplifier is proposed. The goal of this application is the efficiency enhancement at high switching frequency, due to superior conductivity and switching characteristics of enhancement mode GaN FETs over Si devices. Experimental results provided comparison between the performance of GaN FETs on one hand and standard Si MOSFETs and LDMOS transistors on the other. Advantages of GaN devices were experimentally verified as well as the operating conditions (regarding the output power and switching frequency) where these advantages exist.
