Responsibilities

• The wireless RFIC team architects, designs, and validates radio transceivers integrated into wireless SoCs. Our wireless organization is responsible for all aspects of wireless silicon development that transform the user experience at the product level, all of which is driven by an outstanding 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 within the Wireless Radio team, you will be at the center of a wireless SoC design group, giving to Apple’s groundbreaking wireless connectivity solutions into hundreds of millions of products.
• You will provide RFIC designs for wireless SoC and drive them to mass production for Apple’s Wireless Connectivity products. Responsibilities include:
• Hands-on design contributions, from concept, architecture, and topology to transistor-level feasibility studies, power, area and performance trade-off analysis to actual design, simulations, and extractions.
• Design and deliver radio transceiver building blocks and chains, including TX, RX, and PLL-LOGen for wireless connectivity products.
• Work closely with RF Systems on block-level and high-level specifications of the TX RX line-ups and PLL-LOGen and on the accurate distribution of spec margins in the chain.
• Design of RF and Analog loopbacks for calibration and compensation.
• Work through Co-Existence scenarios and design to meet the CoEx requirements.
• We collaborate closely with RFIC test engineers in the setup, debugging, and optimization of the wireless connectivity chip throughout productization.
• Provide design versus silicon measurements correlation and compliance with specifications for volume production.
