Abstract

A method for automatic multi-state hardware conditioning of RFIC PA´s using a single control line is proposed. A gating technique is introduced to allow an on-chip embodiment of envelope feedback, used to simplify circuits and gain calibration requirements. Experimental results obtained with a GaAs IC implementation totaling an area of only 1.4mm² show a potential for single chip integration of this technique.
