A Millimeter-Wave Watt-Level Doherty Power Amplifier in Silicon
IEEE transactions on microwave theory and techniquesThis 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, 2010The 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 ...

Broadband Doherty power amplifiers
2013 IEEE Topical Conference on Power Amplifiers for Wireless and Radio Applications, 2013In 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.

Design of Dual-Band Doherty Power Amplifier Using a New Phase Compensation Technique
IEEE Transactions on Circuits and Systems - II - Express BriefsIn this brief, a novel methodology for designing a dual-band Doherty power amplifier (DPA) is proposed by using different current combining phases between the carrier and peaking power amplifiers (PAs) at different operating frequencies.
