该径向合成器具有宽带、低插损、幅相一致性高、高功率耐受的特点,在宽带大功率合成领域具有广阔的工程应用价值。 | 英文摘要: | Based on the power synthesis theory of coaxial transmission lines and waveguide coaxial transformation, a 6-path directional
combiner is developed. The input end adopts an N-type connector and the output end adopts a double ridge waveguide
form. The model is optimized and simulated using high-frequency electromagnetic field simulation software CST. The processed radial
synthesizer has undergone small signal testing and high-power testing. The test results show that from 4 GHz to 8 GHz frequency
band, the synthetic loss is less than 0. 36 dB, the return loss is less than -10 dB, and the peak power tolerance is higher than
5 kW. This radial synthesizer has the characteristics of broadband, low insertion loss, high amplitude phase consistency and high
power tolerance. It has broad engineering application value in the field of broadband high-power synthesis. | 查看全文 查看/发表评论 下载PDF阅读器 | 关闭 | | | |
