Model-Based Design for Solid State RF Power Transmitters for OFDM Applications

Solid state power amplifier-based transmitters have become very common and with the advancements of GaN devices the power output from the PA has increased and hence they are being used in most of the RF Systems. This paper presents an S-band RF power transmitter using an 8-way power divider and combiner, filter, circulator, and antenna integrated into a single system. The 8-way corporate power divider is simulated using a full wave MoM solver in MATLAB (R) RF PCB Toolbox (TM) and Antenna Toolbox (TM). An OFDM signal is fed to the transmitter and changes in the waveform are reported.
