Abstract: This paper proposed a novel 4 in 1 high power airtight amplifier which worked at watt level for 3 mm band power combination use. This design introduced a silicon based structure to achieve airtightness for W-band components, solving the problem of traditional 3 mm band waveguide components being difficult to be airtight. It was designed by using the airtight waveguide structure. The software was also used for simulating the waveguide combiner. Finally, the power amplifier was carefully fabricated and tested. Results show that the final indicators meet design requirements.

隨著近年來應(yīng)用在3 mm頻段功率器件的制造技術(shù)越來越成熟,,微波單片的輸出功率有了很大的提升,但最大也就在瓦級左右,,所以在一些需要瓦級以上功率輸出的場景時,,往往就需要通過功率合成的方式對多個功率器件的輸出功率進(jìn)行合成后實現(xiàn)。
常用的大功率合成方式為波導(dǎo)合路,,這種功率合成器基于空間合成的技術(shù),,可實現(xiàn)多個模塊輸出功率的一次性高效率合成,具有諸如插入損耗小,、合成效率高,、功率容量大、幅相一致性高和工作頻段易于調(diào)整等特點,。
