Improving the performance of the power amplifier is the most
pressing problem facing designers of modern radio-frequency (RF)
transceivers. Linearity and power efficiency of the transmit path
are of utmost importance, and the power amplifier has proven to be
the bottleneck for both. High linearity enables transmission at the
highest data rates for a given channel bandwidth, and power
efficiency prolongs battery lifetime in portable units and reduces
heat dissipation in high-power transmitters. Cartesian feedback is
a power amplifier linearization technique that acts to soften the
tradeoff between power efficiency and linearity in power
amplifiers. Despite its compelling, fundamental advantages, the
technique has not enjoyed widespread acceptance because of certain
implementation difficulties.
Feedback Linearization of RF Power Amplifiers introduces new
techniques for overcoming the challenges faced by the designer of a
Cartesian feedback system. The theory of the new techniques are
described and analyzed in detail. The book culminates with the
results of the first known fully integrated Cartesian feedback
power amplifier system, whose design was enabled by the techniques
described.
Feedback Linearization of RF Power Amplifiers is a valuable
reference work for engineers in the telecommunications industry,
industry researchers, academic researchers.
