چکیده
Abstract: The efficiency and linearity of power amplifiers based on the LINC technique are discussed. The use of resistive combiners as well as lossless Chireix combiners are detailed and their impact on amplifier linearity and efficiency are highlighted. The tradeoffs between linearity and efficiency in Chireix combiners are investigated experimentally and optimal choice of Chireix combiners is demonstrated. The use of LINC-based power amplifiers for SDR-enabled platforms is discussed.

←− LINC transmitters (LInear amplification with Nonlinear Components) are suitable for the power amplification of variable-envelope signals, since they allow the use of lowcost, highly-efficient strongly-nonlinear power amplifiers. However, the combination of the outputs of the LINC’s two amplifiers has is the weak part of it: the combiner losses offset the amplification efficiency gains inhere...

Outphasing transmitters have been explored to study the trade-off between linearity and efficiency. The outphasing technique enhances efficiency by operating two amplifiers at lower output amplitudes, using two constant envelope signals. Their major drawback is the inherent sensitivity to gain and phase imbalances between the two amplifier branches. Another important issue is related to the deg...

In modern wireless communication systems it is required that the power amplifier could operate with high efficiency, high linearity, and low harmonic output level simultaneously. To increase efficiency of the power amplifier, a switching-mode Class E mode technique can be applied. This kind of a power amplifier requires an operation in saturation mode resulting in a poor linearity, and therefor...
