A Millimeter-Wave Watt-Level Doherty Power Amplifier in Silicon

IEEE transactions on microwave theory and techniques
This article presents a millimeter-wave (mmWave) power-combined Doherty power amplifier (PA) topology. To reach watt-level output power and simultaneously enhance back-off efficiency, we propose a multifunctional PA network based on an extended rat-race ...

Designing a Doherty power amplifier

Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference, 2010
The aim of this paper is to present an easy and rigorous way to design a Doherty power amplifier (DPA) starting from the requirements of the wireless system, in which it has to be integrated. In particular, accounting for the value of the pick to average power ratio (PAPR) of the system, design guidelines will be given to correctly address each design ...

Design of a Fully Integrated Wideband Continuous-Mode Asymmetrical Doherty Power Amplifier in GaN-on-SiC HEMT Technology

IEEE Transactions on Circuits and Systems - II - Express Briefs
In this brief, a novel continuous-mode asymmetrical Doherty power amplifier (CM-ADPA) is proposed. It is illustrated that by applying complex impedance at the power combining node, the continuous-mode impedance condition can be obtained for the main ...

Broadband Doherty power amplifiers

2013 IEEE Topical Conference on Power Amplifiers for Wireless and Radio Applications, 2013
In this paper, the transformer-less load-modulated (TLLM) architecture for designing broadband Doherty amplifiers is presented. In this architecture, the quarter-wave impedance transformers of the Doherty amplifier are not used. As a result, the design will be much more compact and large operational bandwidths can be obtained.
