ABSTRACT:  This talk will describe the advances on this topic within the FDCRGP “Research and Development of Doherty Power Amplifier based Broadband Highly Efficient and Linear Transmitter Front-end for 5G and millimeter wave Applications .” The emergence of the next generation of wireless systems (such as 5G) rely on advancements of multiple technologies. In general, two broad critical directions in the advancement of 5G are the telecommunication engineering protocols and the associated circuits operating at Radio frequencies (RF) and other high frequency bands to realize those protocols. This project envisaged to successfully realize front-end circuit modules for 5G centric applications. The plan was to emphasize on the key front-end component Power Amplifier and propose innovative solutions to support transmission of telecommunication signals (voice, data, multimedia) with excellent quality. This project therefore entailed development of a number of circuit components such as power divider, power combiner, impedance transformers, junction dividers, power amplifier modules, predistorters etc. All of these were successfully developed in various configurations and were eventually assembled to develop the fully functional front-end modules at 5G frequency bands. This talk will briefly go through some of these developments and the future challenges associated with the emerging wireless standards.
