This involves designing beyond classic class-AB, using techniques like envelope tracing or envelope elimination and restoration (EER, or polar transmitter). You will work on architecting various calibration and correction methods for hardware/firmware implementation and validate overall performance enhancement through lab measurements. Collaboration with RF/analog designers, software/firmware engineers, digital designers, product engineers, and architects is crucial. The role also involves realizing methods with power and area efficient digital implementations and high-efficiency software implementations, possibly with hardware acceleration, and bringing up, testing, characterizing, and optimizing real silicon in the lab.

  • Experience in designing signal processing for wireless communications systems
  • Understand methods to estimate RF impairments via equipment measurement or self-testing
  • Experience with MATLAB, Python, or C/C++ for algorithm development
  • Hands-on lab testing & characterization experience (spectrum analyzer, signal generator, etc.)
  • Understanding of RF/analog components, their impairments, and calibration methods
Good to have:
  • MSEE/PhD with relevant experience
  • Proven track record of optimization algorithms and RF calibration applications
  • Experience with digital predistortion, crest-factor reduction, nonlinear crosstalk/interference cancellation, and real-chip bring-up
  • Understanding of communication theory & signal processing algorithms
  • Knowledge of wireless communication protocols (5G-NR/LTE/WCDMA/GSM, 802.11 WiFi, Bluetooth/BLE)
  • Coursework and experience in circuit design
Perks:
  • Discretionary employee stock programs
  • Discretionary restricted stock unit awards
  • Discounted Apple stock purchase
  • Comprehensive medical and dental coverage
  • Retirement benefits
  • Discounted products and free services
  • Reimbursement for certain educational expenses
  • Discretionary bonuses or commission payments
  • Relocation assistance
