Broadband GaN Doherty Power Amplifier With Integrated Unequal Wilkinson and λ/4 Phase Network for Midband 5G

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)

Digital Predistorter Implementation for Wideband Power Amplifiers in New Generation Wireless Systems Based on a Low‐Complexity Volterra Series Model

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.

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 ...

Binary Search‐Based Division (BSBD): A Technique for Efficient Division in Hardware

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
The division techniques play a key role in several computer‐implemented algorithms and applications; regrettably, they impose significant implementation constraints that hinder parallelization. The proposed binary search‐based division (BSBD) technique is inherited from the variable latency dividers, which have the potential to adjust the quotient bit ...

Intra‐scan RF power amplifier drift correction

Magnetic Resonance in Medicine, Volume 92, Issue 2, Page 645-659, August 2024.
Abstract Purpose The drift in radiofrequency (RF) power amplifiers (RFPAs) is assessed and several contributing factors are investigated. Two approaches for prospective correction of drift are proposed and their effectiveness is evaluated. Methods RFPA drift assessment encompasses both intra‐pulse and inter‐pulse drift analyses.

Long baseline bistatic radar imaging of tumbling space objects for enhancing space domain awareness

IET Radar, Sonar &Navigation, Volume 18, Issue 4, Page 598-619, April 2024.
This paper describes long baseline bistatic radar measurements using the Millstone Hill Radar (MHR) in the USA, the Tracking and Imaging Radar (TIRA) in Germany, multiple receivers of the e‐MERLIN array in the United Kingdom, and the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands.

A Novel Approach of Optimal Signal Streaming Analysis Implicated Supervised Feedforward Neural Networks

IET Signal Processing, Volume 2024, Issue 1, 2024.
The analysis and interpretation of enormous amounts of data generated by 5G networks present several challenges related to noise, precision, and feasibility validation. Therefore, this study aims to evaluate the effectiveness of channel equalisation in the network and enhance it by distributing signals over all subcarriers and symbols.
