The RF frontend antenna combination is a vital part of a mobile phone because its performance is very relevant to the link quality between handset and cellular network basestations. The RF frontend performance suffers from changes in operating environment, like handeffects, that are often unpredictable.Adaptive RF FrontEnds for HandHeld Applications presents an analysis on the impact of fluctuating environmental parameters. In order to overcome undesired behavior two different adaptive control methods are treated that make RF frondends more resilient: adaptive impedance control, and adaptive power control.Several adaptive impedance control techniques are discussed, using a priori knowledge on matching network properties, in order to simplify robust 2dimensional control. A generic protection concept is presented, based on adaptive power control, which improves the ruggedness of a power amplifier or preserves its linearity under extremes. It comprises overvoltage, overtemperature, and undervoltage protection.
