Abstract :
A power amplifier is implemented using a SiC Graphene Field-Effect Transistor. The amplifier gain is enhanced using an input matching LC circuit, which is connected to the GFET through standard RF probes. Experimental measurements and ADS-simulation based on developed models are used for the evaluation of the performances of the SiC GFET-based amplifier. It has been shown that a power gain of 4.8 dB can be achieved at 2.4 GHz using the GFET and the matching circuit assembly. Technology parameters are studied towards the improvement of the amplifier´s figures of merit.
