چکیده

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.

OUTPHASING TRANSMITTER An Outphasing Transmitter Using Class - E PAs and Asym - metric Combining : Part

H igh efficiency linear amplification is of great interest in modern communication systems as it increases talk time, decreases power consumption , decreases heat dissipation, and improves reliability. The efficiency of linear power amplifiers (PAs) is highest at the peak output power (PEP) and decreases significantly for low amplitudes, as shown in Figure 1. Signals with time-varying amplitude...

Power Amplifiers for Next Generation Wireless Platforms

Class-E amplifier has the potential to deliver high efficiency required for the next generation wireless systems. In this journal, we discuss a novel load pull analysis technique to characterize the efficiency performance of Class-E amplifier in an outphasing power combining scheme. Class-E amplifier is not an ideal current or voltage source as is required for the traditional analysis of outpha...
