About the position

The RFIC - PLL Design Engineer will be a key member of the Wireless Radio team at Apple, responsible for designing and validating radio transceivers integrated into wireless SoCs. This role involves leading the design of analog and digital PLL solutions, driving performance metrics, and collaborating with cross-functional teams to innovate wireless connectivity solutions that enhance user experience across Apple products.

Responsibilities

• Lead design of radio transceiver chains including analog PLLs, VCOs, digital PLLs, DCOs, LOGen, and chain of blocks in RX and TX.
• Drive radio KPI (power, area, performance) to meet product requirements.
• Work with multi-functional teams to define radio features enabling wireless innovation.
• Collaborate closely with RF Systems on block-level and high-level specifications of the PLL-LOGen, TX, and RX line-ups.
• Contribute hands-on to design, simulations, and extractions from concept to actual design.
• Responsible for floorplan layout and verification of the design to ensure successful tape-out.
• Provide design versus silicon measurements correlation and compliance with volume production specifications.

Requirements

• BS degree in Electrical Engineering or related field and 3+ years of relevant industry experience.
• Experience with RF/analog and mixed-signal design in RF CMOS technology.
• Hands-on experience designing TDC, GRO, Digital Filters, Sigma Delta Modulators, Pre-scalers, MMD, DCOs, PFD-CP, and VCOs.
• Skilled in using Cadence Virtuoso, Spectre RF, Matlab, and EM simulation tools.

Nice-to-haves

• Direct experience in designing and bringing wireless transceivers into mass production in deep sub-micron RFCMOS technology.
• Extensive knowledge in fractional N synthesizer and LOGen silicon characterization and debugging.
• Deep understanding of analog, mixed-signal, and RF circuit design including LNAs, PAs, mixers, and baseband filters.
• Familiarity with various RF transceiver architectures and their trade-offs.
