EDI CON Experts Present State-of-the-Art Techniques to Address RF Power Amplifier Efficiency and Linearization

The efficiency and linear performance of RF power amplifiers using traditional architectures may be unacceptable for future wideband LTE-Advanced applications. Consequently, extensive efforts are underway within the wireless industry to enhance these metrics by a variety of techniques e.g. Doherty, envelope tracking etc.  Such techniques have been reported to improve overall amplifier performance significantly. Considerations of new RF PA architectures and design techniques for wideband wireless applications will be the focus of several technical sessions and workshops offered by international experts presenting at the Electronic Design Innovations Conference (EDI CON)  from March 12 -14 at the Beijing International convention Center.

Join RFIC /MMIC semiconductor design engineers from Freescale, TriQuint, Nitronex, M/A-Com Technology Solutions, and Microsemi as well as RF RDA simulation experts from Agilent and AWR as they discuss the challenges and opportunities enhanced PA performance for wideband applications.
