artifact description
The primary purpose of this research was to study the power gain and efficiency of microwave power amplifier for personal communication devices by using simulation software. In the power amplifier circuit designs, the power gain and efficiency of power amplifier are significant factors. The Doherty configuration and matching components for both input and output of the system are the main techniques use for the thesis research. The Doherty configuration uses two transistors to optimize the total output gain. The matching technique provides the maximum gain at the target frequency. The individual stability consideration for transistors was calculated by MatLab script in order to meet the requirement for microwave circuit design. The simulation software, PUFF, was used as the simulation tool. The circuit simulation results were introduced at target frequency 2.1 GHz. The bandpass filter designs also integrated into the circuits in order to eliminate the frequencies outside the band.
