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.

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.
