Ka频段160W固态功率放大器的研制
Development of Ka-band 160 W Solid-state Power Amplifier
摘要
Abstract
In view of the high throughput and wide coverage of Ka-band satellite communication system,a Ka-band 160 W solid-state power amplifier is introduced.The power amplifier adopts the waveguide-microstrip dual-probe design and the wave-guide power distribution/synthesizer based on the micro-strip magic T.The eight GaN power amplifier chips are combined to finally realize the continuous wave output power signal of more than 160 W in the 27.0 GHz～31.0 GHz operating frequency band.Using the analog predistorter,the third-order intermodulation index of the whole machine is better than-31dBc,and the index is excellent.The output waveguide of the power amplifier adopts the standard WR-28 interface,with perfect monitoring and protection mea-sures,high reliability,and is suitable for satellite communication and other launch systems.关键词
