This Mini-Special Issue of the IEEE Transactions on Microwave Theory and Techniques (TMTT) includes five articles that have been expanded from innovative works presented at the 2021 Radio Frequency Integrated Circuits Symposium, which was held in June 2021. After over a year of virtual conferences, the 2021 RFIC Symposium was held both virtually and in-person in Atlanta, GA, USA. The hybrid format offered panels, technical lectures, interactive workshops, and 14 engaging technical sessions to attendees and authors. All virtual events were live-streamed. The opportunity to attend in both formats was only possible with the diligence, creativity, and excellent leadership of the 2021 General Chair, Brian Floyd, and the Technical Program Chair and Co-Chair, Osama Shana’a and Donald Lie.

RFIC 2021 客座社论


IEEE 微波理论与技术汇刊 (TMTT) 的迷你特刊包括五篇文章，这些文章是根据 2021 年 6 月举行的 2021 年射频集成电路研讨会上发表的创新作品扩展而来的。经过一年多的虚拟讨论会议期间，2021 年 RFIC 研讨会在美国佐治亚州亚特兰大以虚拟和现场方式举行。这种混合形式为与会者和作者提供了小组讨论、技术讲座、互动研讨会和 14 场引人入胜的技术会议。所有虚拟活动均进行现场直播。只有凭借 2021 年大会主席 Brian Floyd 以及技术项目主席兼联合主席 Osama Shana'a 和 Donald Lie 的勤奋、创造力和卓越领导力，才有机会以两种形式参加。
