Description: 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.
