GNSS RFIC Design Engineer

Santa Clara Valley (Cupertino), California, United States


Role Number:200159128
Would you like to join Apple’s growing wireless silicon development team? Our wireless SOC organization is responsible for all aspects of wireless silicon development with a particular emphasis on highly energy efficient design and new technologies that transform the user experience at the product level, all of which is driven by a world-class vertically integrated engineering team spanning RF/Analog architecture and design, Systems/PHY/MAC architecture and design, VLSI/RTL design and integration, Emulation, Design Verification, Test and Validation, and FW/SW engineering. As an RFIC design engineer, you will be at the center of a wireless SoC design group. You will have a critical impact on getting Apple’s state-of-the-art radios into hundreds of millions of products.

Key Qualifications

  • Typically requires at least MS + 4 years of experience or a PhD in the area of RF/Analog IC design with advanced CMOS technology nodes.
  • Deep understanding of RFIC circuit design. Direct tape-out experience with one or more of the following blocks: RF front-end circuits, PA, LNA, mixer, oscillator, PLL, LO, VGA, filter, TIA and/or other baseband analog blocks in deep sub-micron CMOS technology.
  • Hands-on experience in GNSS RFIC and RF systems design and familiarity with RF coexistence in a cellular and mobile wireless device is critical to have.
  • Deep understanding of analog design concepts such as analysis of noise, linearity, mismatch, stability and other analog impairments.
  • Deep understanding of CMOS device physics, RF device modeling, device noise parameters, inductor modeling.
  • Insights into packaging effects, supply isolations, high frequency ESD structures, and circuit layout for optimum RF performance.
  • Familiarity with various RF transceiver architectures and their trade-offs, as well as calibration methods used for different RF transceiver architectures.
  • Familiarity with Cadence Virtuoso, Spectre RF, EMX and similar tools.
  • Understanding of system specifications and ability to work with system architects to translate system requirement into circuit requirement at IC level.
  • Experience in Si characterization and debug.


As a GNSS RF IC design engineer and a key member of a small RFIC team, you will research, design and bring the next-generation wireless SoCs into high-volume production at advanced CMOS technology nodes. Responsibilities include: - Design of analog and/or RFIC blocks. - Overseeing the layout and verifying the design to ensure a successful tape-out. - Testing the design and debugging the issues that may arise from early development stages through productization. - Collaborating with the system group to define the requirements for RF and baseband blocks based on the system requirements. - Working with the technology team to understand the capabilities and limits of the technology node to achieve the optimum performance.
