International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.This paper presents the design and implementation of a high‐efficiency two‐way Doherty power amplifier (DPA) for sub‐6 GHz 5G New Radio (NR) applications, specifically targeting the n78 band (3.3–3.8 GHz). The proposed gallium nitride (GaN)‐based DPA delivers a peak output power of 42.5 dBm, a gain of 13.3 dB, and a maximum power‐added efficiency (PAE)

Optimization of Tone Reservation-Based PAPR Reduction for OFDM Systems [PDF]
Radioengineering, 2017 A major drawback of orthogonal frequency division multiplexing (OFDM) is its high peak-to-average power ratio (PAPR). Tone reservation (TR) is one of the numerous methods for reducing the PAPR.

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 38, Issue 5, September/October 2025.ABSTRACT In this article, we provide a novel, expanded, and adapted pruning approach for the Simplified Volterra Series (SVS) model that makes it applicable to a wider range of Power Amplifiers (PAs). The proposed Modified SVS (MSVS) model is then applied in a Digital Predistortion (DPD) architecture to linearize a 25 W Gallium Nitride (GaN) RF PA.

DE BRUIJN SEQUENCE BASED PEAK POWER CONTROL AND INTERFERENCE MITIGATION IN MC-CDMA SYSTEM [PDF]
Journal of Engineering Science and Technology, 2015 In Multicarrier Code Division Multiple Access (MC-CDMA) system, the performance can get degraded due to a high Peak to Average Power Ratio (PAPR) which is equivalent to Peak to Mean Envelope Power Ratio (PMEPR) and Multi Access Interference (MAI).

Performance Analysis of MIMO Links With Non‐Isolated Active Antenna Arrays
Microwave and Optical Technology Letters, Volume 67, Issue 8, August 2025.ABSTRACT In this paper, we analyze the performance of non‐isolated active arrays in a multiple‐input multiple‐output (MIMO) system. When ferromagnetic‐type isolators are removed in the transmitter (Tx) chains, the antenna mutual coupling will dynamically change the load impedance seen by the power amplifiers (PAs) at their outputs, which subsequently ...
