本文讨论了未来5G基站所需的宽带毫米波发射机的跟踪解决方案。其独特之处是在调制器中使用基于GaN器件的开关型电路。从2 GHz频段的最新结果开始，讨论了带宽超过1 GHz的30 GHz发射机的先进解决方案的潜力。考虑了离散级G类和S类调制器。
This paper discusses envelope-tracking solutions for broadband mm-wave transmitters as required in future 5G base stations. The unique feature is to use switch-type circuits based on GaN devices in the modulators. Starting from state-of-the-art results in the 2 GHz band, the potential of advanced solutions for 30 GHz transmitters with bandwidths beyond 1 GHz is discussed. Both discrete-level class-G and class-S modulators are considered.
