Development of 100W Solid State Power Amplifier at 13.56?1MHz

Abstract

Project aim is the development of a common source class B, cwrf amplifier by using MOSFET. The work includes literature survey, concept, simulation, design, fabrication and testing of the power amplifier. This single stage amplifier of more than 100W output and gain 13dB needs development in the frequency range of 13.56?1MHz. A temperature sensor at the heat sink mounting must be added along with necessary wiring to switch off the dc supply and thereby protecting the circuit in case of overheating. The ultimately developed amplifier needs testing for the frequency response, power gain and output wave shapes etc. by using a set of appropriate instruments.
