$150
- 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 techniques.
- 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 interact with RF/analog designers, software or firmware engineers, digital designers, product engineers and architects to define and specify parts in the wireless systems.
- Implement system models of the analog front-end design, impairments and come up with right controls and calibrations in C and MATLAB for optimal system performances.
