Job Description:
SummaryPosted: Aug 28, 2024Role Number: 200539415Would you like
to join Apple's growing wireless silicon development team? The
wireless RFIC team architects, designs, and validates radio
transceivers integrated into complex 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 a best-in-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 Sr. RFIC - PLL Design
Engineer within the Wireless Radio team, you will be at the center
of a wireless SoC design group with a critical impact on getting
Apple's state-of-the-art wireless connectivity solutions into
hundreds of millions of products.DescriptionDescriptionAs a Senior
RFIC-PLL Designer, you are going to be responsible for providing
analog and digital PLL solutions for wireless SoC and driving them
to mass production for Apple's Wireless Connectivity products.
Responsibilities include: - Lead design of radio transceiver chains
including analog PLLs - VCOs, digital PLLs - DCOs, LOGen, and chain
of blocks in RX and TX for wireless connectivity products. - Drive
radio KPI (power, area, performance) to meet product requirements -
Work with cross-functional teams including platform architecture,
wireless design, RF HW and SW to define radio features enabling
wireless innovation. - Work closely with RF Systems in block level
and high level specifications of the PLL-LOGen, TX and RX line ups,
and proper distribution of spec margins in the chain. - Hands-on
design contributions starting from concept, architecture and
topology to transistor-level feasibility studies and KPI trade-off
analysis to actual design, simulations and extractions. - Design of
RF and Analog loopbacks for calibration and compensation. - Work
through Co-Existence scenarios and design to meet the CoEx
requirements. - Oversee the floorplan layout and verification of
the design to ensure a successful tape-out. - Close collaboration
with RFIC test engineers in the bring up, debug and optimization of
the wireless connectivity chip through the productization. -
Provide design versus silicon measurements correlation, and
compliance with specification for a volume production.Minimum
