Linearization of the Fifth Generation Power Amplifiers by Injection of the Second Order Digitally Processed Signals

Autor: A. Atanaskovic, A. Djoric, N. Males Ilic, B. P. Stosic, D. Budimir

Publikováno v: Radioengineering, Vol 33, Iss 3, Pp 339-348 (2024)

This paper conducts a validation of two linearization approaches that utilize baseband nonlinear linearization signals of the 2nd order, through practical experiments on an asymmetrical two-way microstrip Doherty amplifier (ADA), and simulations on a

Autor: Seungmin Woo, Woojin Choi, Jaekyung Shin, Yifei Chen, Youngchan Choi, Sooncheol Bae, Hyungjin Jeon, Youngyun Woo, Youngoo Yang

Publikováno v: Journal of Electromagnetic Engineering and Science, Vol 24, Iss 4, Pp 401-410 (2024)

Owing to the high impedance transformation ratio, the Doherty power amplifier (DPA) with a large output power back-off generally has bandwidth limitations. This study proposes an asymmetric DPA with an impedance distribution and control circuit (IDCC

A Hybrid Integrated and Low-Cost Multi-Chip Broadband Doherty Power Amplifier Module for 5G Massive MIMO Application

Autor: Fei Huang, Guansheng Lv, Huibo Wu, Wenhua Chen, Zhenghe Feng

Publikováno v: Engineering, Vol 38, Iss , Pp 223-232 (2024)

In this paper, a hybrid integrated broadband Doherty power amplifier (DPA) based on a multi-chip module (MCM), whose active devices are fabricated using the gallium nitride (GaN) process and whose passive circuits are fabricated using the gallium ars

On the design and linearization of transmitters for the LTE 450 base station

Autor: Dawid Rosołowski, Daniel Gryglewski, Wojciech Wojtasiak, Michał Kajczuk, Jędrzej Klocek

Publikováno v: International Journal of Electronics and Telecommunications, Vol vol. 70, Iss No 3, Pp 707-713 (2024)

The paper presents the two transmitter analog paths of 10 W and 400 W peak output power developed for micro- and macro-cell LTE450 base stations, respectively. Each path contains a chain of amplifiers with a final stage designed in the Doherty archit
