About this role

DSP Wireless Systems Engineer Sunnyvale, United States of America At Apple, we work every single day to craft products that enrich people's lives. Do you love working on challenges that no one has solved yet? Do you like changing the game? We have an opportunity for a forward-thinking and exceptional DSP Wireless System Engineer. As a member of our multifaceted group, you will have the rare and extraordinary opportunity to craft upcoming products that will delight and encourage millions of Apple's customers every single day. For wireless system, power amplifiers (PA) in the transmitter are the main source of power consumption. To improve efficiency, PA must be designed beyond the classic class-AB, together with enhancement using envelope tracing, or envelope elimination and restoration (EER, or polar transmitter). Those designs come with impairments or nonlinear distortion that need to be clean up using digital signal processing (DSP) techniques. The optimization and calibration of those DSP techniques are the critical to achieve high performing systems. In this technical role, you will be at the center of a silicon design group responsible for using digital algorithm or method to improve the PA efficiency, reducing power consumption, but with acceptable linearity for high data rate applications. You will mainly work on architecting various calibration and correction methods for implementation in hardware/firmware and validation of overall performance enhancement through lab measurement. You will collaborate RF/analog designers, software or firmware engineers, digital designers, product engineers and architects to define and specify parts in the wireless systems.
