A trade-off between linearity and efficiency exists in conventional power amplifiers. The outphase amplifying concept overcomes this trade-off by enabling the use of high efficiency, non-linear power amplifiers for linear amplification. An amplitude modulated signal is first decomposed into two constant amplitude, phase modulated signals that can be amplified using two high efficiency switching...
Broadband GaN Class-E Power Amplifier for Load Modulated Delta Sigma and 5G Transmitter Applications
In this paper, a highly efficient prototype of Gallium Nitride high electron mobility transistor (GaN HEMT) power amplifier using elliptic low pass filter output network is proposed, fabricated and measured. A fifth-order elliptic low-pass filter network is designed and implemented for the output matching, which provides optimized fundamental and harmonic impedances. Simulation and experimental...
This paper presents an analysis of a reconstruction filter in a switched mode power amplifier system. Doubly and singly terminated filters for current-mode class-S power amplifiers were analysed previously through analytical, numerical, and experimental approaches, and it was shown that only singly terminated filters can fulfil the requirements of current-mode switching amplifiers, owing to the...
