Abstract

The microwave power source is widely used for heating and dryness, etc. so far. To solve problem (high voltage and short life time, difficult control) of the magnetron used now, semiconductor (GaN-HEMT, LDMOS) is examined. It is necessary to combine several modules to get 1kW, because the output power of semiconductor devices is about 200W. When output power and phase of each module are different, we analyzed the combined output power. We achieved 1.2kW output power by controlling the output of each module.
