Supply- and Load-Modulated Balanced Amplifier for Efficient Broadband 5G Base Stations
IEEE Transactions on Microwave Theory and Techniques(2019)
摘要
This paper presents a broadband efficient power amplifier (PA) targeting sub-6-GHz 5G base station applications. Due to the demanding requirements in both peak-to-average power ratio (PAPR) and bandwidth in 5G systems, we employ a combination of both load and supply modulation for efficiency enhancement. Active matching, implemented using an RF-input load-modulated balanced amplifier (LMBA) archit...
