摘要：

This paper describes a new type of PA-module which contains a predistortion function and the application to N-CDMA handset terminals. The predistortion technology is based on look-up-table method using the input and output signal envelopes and can operate independent from the base-band block. By omitting the adaptative predistortion for AM/PM, and integrating main controlling functions on CMOS IC chip, the predistortion technique has been realized in a PA-module. The PA-module has been achieved the power added efficiency (PAE) of 48% at the output power of 27.5dBm. This PAE is extremely high in comparison with the conventional PA-module for N-CDMA.
