Abstract: “In this paper, we introduce an overview of wireless power transmission for Solar Power Satellite. Specially, We present the study, design and fabrication of a 355W multi stage S – band solid – state power amplifier to be used for Solar Power Satellite. The power amplifier module with 45W peak output power is used as the basic cell of the amplification. Combining 8 of these modules, we achieve 355W. The design and simulated results were carried out by the microwave engineering professional design software, known as ADS2009 package. All simulations and experimental results will be reported.”

Keywords: microwave power transmission, power amplifier, wilkinson divider/combiner.
