A Compact and Broadband Doherty Power Amplifier Without Post-Matching Network
IEEE Transactions on Circuits and Systems - II - Express Briefs, 2023Post-matching network (PMN) dominates broadband Doherty power amplifier (DPA) design, but at the cost of large footprint. This brief presents a PMN-free, compact and broadband DPA based on dual-mode impedance transformer (IT) which can simultaneously ...

Broadband power-equalization amplifier
2012 International Conference on Microwave and Millimeter Wave Technology (ICMMT), 2012The paper presents a new method to design microwave gain equalizer with terminal open line resonators. By changing the electrical length of main transmission line in a certain range, the return loss is improved obviously while transmission parameter changes slightly.

A unique MMIC broadband power amplifier approach
IEEE Journal of Solid-State Circuits, 1993A broadband monolithic microwave integrated circuit (MMIC) power amplifier design approach is described using lossy matching networks in the form of a bridged-T all-pass network. This approach offers the advantage of exceptional gain flatness, good input VSWR, high efficiency, and small size.

Broadband doherty power amplifier and linearization
2016 46th European Microwave Conference (EuMC), 2016This paper will review the recent progress in broadband Doherty power amplifier (PA) and low feedback sampling rate digital predistortion (DPD) techniques. Continuous mode impedance matching method is proposed for Doherty PA for bandwidth enhancement, which utilizes the cross-matching technique to realize the physical output matching network.
