MaXentric Designs and Optimizes Envelope Tracking PAs for 5G LTE Using NI AWR Software


​MaXentric Technologies, LLC, a specialty R&D firm, has developed an envelope tracking power amplifier (ETPA) using real-time efficiency and linearity measurements for optimizing ETPA design, with flexibility to accommodate different 5G signals. The use of NI AWR Design Environment™, specifically Microwave Office circuit design software and AXIEM 3D planar EM simulator, enabled the designers to significantly reduce PA optimization time without sacrificing measurement accuracy. The close correlation between simulation and measurement enabled them to perform most of the optimizing in software before physically implementing it on the board, thus reducing the number of iterations that had to be performed.

“NI AWR Design Environment enhances the designer’s experience by significantly reducing optimization time,” said Johana Yan, lead engineer at MaXentric. “In addition, in envelope tracking, the ability to simultaneously simulate one’s design at the chip, board, and system level has become paramount in enabling next-generation wideband high-efficiency PA design.’’
