Improving performances and reducing cost for power amplifiers in millimeter wave

摘要

The high power broadband amplifiers are key devices for millimeter wave system and equipment. The significant progresses for broadband amplifier-high power TWT in MMWs are described. Advanced techniques such as enhancing operating bandwidth, reducing cost, increasing efficiency, improving heat transfer capability, suppressing spurious oscillations and raising beam transmission have been developed. These approaches possess important consult value to designer for MMW power amplifiers.
