Highly efficient 3-stage Doherty power amplifier using gate bias adaption
Ildu Kim, Junghwan Moon, Jungjoon Kim, Seunghoon Jee, Junghwan Son, Bumman Kim
This paper demonstrates a highly efficient 3-stage Doherty power amplifier (PA) employing an envelope tracking (ET) technique. The ?3-stage? Doherty PA is the most efficient architecture for a high peak-to-average power ratio (PAPR) signal among the various Doherty PAs. However, because of the lower peaking biases than those of the ?N-way? Doherty PA, the proper load modulation is hard to be achie
The multi-antenna code multiplexing front-end: theory and performance
Matthieu Gautier, Guillaume Villemaud, Ioan Burciu
In this paper, we address the architecture of a multi-antenna receiver and we aim at reducing the complexity of the analog front-end. To this end, an innovative architecture is introduced based on code multiplexing. This architecture uses the direct sequence spread spectrum technique in order to multiplex the different antennas contributions through a single In-phase/Quadrature (IQ) demodulator. S
