A Power Re-Use Technique for Improved Efficiency of Outphasing Microwave Power Amplifiers
An improved power re-use technique is introduced for application to outphased microwave power amplifiers. The technique allows a significant portion of the wasted out-of-phase components of the signal to be returned to the power supply, resulting in substantial improvements in overall power-amplifier efficiency. A peak re-use RF-to-DC efficiency of 63% was obtained at 1.96 GHz.
متن کاملDesigning Highly-linear Microwave Power Amplifiers Based
This paper shows how intermodulation distortion, IMD, sweet spots can be used as a practically meaningful technology to design highly linear microwave power amplifiers. It starts by reviewing the physical origins of these points of large signal to nonlinear distortion ratio, distinguishing the ones uniquely determined by the active device’s quiescent point – small-signal IMD sweet spots – from ...
متن کاملLoad Pull Methodology to Characterize Class-E Outphasing Power Amplifiers
A novel load pull methodology to characterize the performance of class-E outphasing power amplifiers is presented. The traditional analysis of the outphasing topology cannot be applied when classE amplifiers are used because these amplifiers do not behave as an ideal current or voltage source. Unlike most other amplifier classes, class-E amplifiers require a phase modulated input signal with co...

15 صفحه اولFour-Way Substrate Integrated Waveguide (SIW) Power Divider/Combiner for High Power Applications
A four-way power divider/power combiner using substrate integrated waveguide (SIW) and microstrip lines is proposed and investigated. The proposed power divider consists of a double-layer substrate with a bottom layer including an SIW T-junction and a top layer including a microstrip network. This microstrip network consists of a modified Gysel power divider which provides a high isolation betw...
