Abstract

This paper proposes a more precise way of radiofrequency output power control and sensing for mobile base station transmitters without increasing the complexity of the AGC of their power amplifier in order to overcome the design adjustment problems and the production ones. The solution presented is based on measuring both the output power RF and the current consumption of the PA. The solution has been tested on commercial GSM triple-band fixed cellular terminals and prototypes of 3G power amplifiers.
