Multimode multiband power amplifier module integrated duplexer for mobile applications

A multi-mode multi-band (MMMB) power amplifier module with integrated duplexer (PAMiD) is developed for mobile handset applications. To reduce size and improve RF performance of Tx front-end, the PAMiD consolidates most of the post-PA networks as well as PA block in a single module. This paper summarizes the RF requirements and challenges addressed in recent years that pursue PAMiD development, and discusses its design consideration.
