Flexible and reconfigurable transmitters with multimode and multiband capability are indispensible to handle the evolving wireless communication systems. To meet the stringent requirements of the systems, digitally enhanced linear power amplifiers (PAs) have received considerable attention because of their digital flexibility and capability. In this paper, we review the key architectures in this area: the delta-sigma digitized polar transmitter and the envelope tracking (ET) technique for multimode operation. The broadband PA is also described for multiband operation with an ET transmitter. The multimode and multiband operation of the broadband PA is demonstrated. This paper covers the basic concepts of flexible PA architectures and their current research status.
