Millimeter-Wave GaN Power Amplifier MMICs for 5G Application
2019 IEEE International Symposium on Circuits and Systems (ISCAS)(2019)
摘要
The fifth generation mobile communications (5G) are expected to accommodate the forthcoming huge traffic demands, and the massive multiple input multiple output (MIMO) technology utilizing hundreds of antenna elements has drawn attention as a key antenna configuration for envisioned 5G. In order to realize the active phased array antenna (APAA), three kinds of small size millimeter-wave GaN power amplifier (PA) MMICs are prototyped, and they are single-ended PA MMICs for high power and high linearity, respectively, and Doherty PA MMIC for high efficiency. To the best of author's knowledge, the prototyped PA MMICs are state-f-the art 5G amplifiers at Ka-band
