Integral study of GaN amplifiers and antenna technique for high power microwave transmission

摘要

The microwave transmission recently requires a high power RF circuit and antenna system based on continuous wave (CW) for wireless power supply and space satellite applications. The GaN amplifiers and antenna technologies are necessary for the high power microwave transmission. In the modern works, these technological fields have been considered as the different field. In this work, the integration of the design methods of GaN amplifier and RF antenna technologies is studied. In addition, the GaN amplifier and RF antenna are comprehensively designed for the high efficiency and effective microwave transmission. In particular, the following programs are discussed in this work: the high power GaN amplifier design based on a combiner technique for CW operation; the high efficiency GaN amplifier design and integration with an antenna for beam combining in a free space based on active array antenna techniques; the sidelobe reduction based on the active antenna techniques.
