About the role

As a RFIC Design Engineer, you are going to be responsible for providing RFIC solutions for wireless SoC and driving them to mass production for Apple’s Wireless Connectivity products.

The wireless RFIC team architects, develop, and validates radio transceivers integrated into sophisticated wireless SoCs. Our wireless organization is responsible for all aspects of wireless silicon development.

It transforms 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 engineer within the Wireless Radio team, you will be at the center of a wireless SoC design group, chipping in to Apple’s innovative wireless connectivity solutions into hundreds of millions of products.

Responsibilities

• Drive radio KPI (power, area, performance) to meet product requirements.
• Work with multi-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 TX and RX line ups and PLL-LOGen, and accurate distribution of spec margins in the chain.
• Design and deliver radio transceiver building blocks and chains, including TX, RX, and PLL-LOGen for wireless connectivity products.
• Design of RF and Analog loopbacks for calibration and compensation.
• Deep understanding of various Co-Existence scenarios and design requirements to meet the CoEx requirements.
• Be responsible for the floorplan layout and verification of the design to ensure a successful tape-out.
• Provide design versus silicon measurements correlation, and compliance with specification for a volume production.

Minimum Qualifications

• BS and 10+ years of relevant industry experience.
• Deep understanding of analog design concepts such as analysis of noise, linearity, mismatch, stability, and other analog impairments.
• Experienced in Cadence Virtuoso, Spectre RF, Matlab, EM simulation (EMX, HFSS), and similar tools.
• Direct experience in crafting and bringing into mass production of wireless transceivers in deep sub-micron RFCMOS technology.

Deep understanding of analog, mixed-signal and RF circuit design. This includes design of LNAs and PAs, PLL/VCO/DCO/LOGEN blocks, mixers, baseband filters and amplifiers, data converters and calibration methods associated with such high performance wireless systems.

Preferred Qualifications

• MSEE and PhD plus relevant industry experience.
• 10+ years of RF/analog and mixed-signal design experience in groundbreaking RF CMOS design.

Familiarity with various RF transceiver architectures and their trade-offs, system specifications, and ability to work with system architects to translate system requirements into circuit requirements at IC level; strong understanding of impact of modulation type to radio architecture and requirements.

• Proven capability working with digital design group for an optimum partition between digital and analog domain.
• Familiarity with the integration flows and challenges of wireless SoCs.
• Extensive experience in Silicon characterization and debug.
• Ability to drive strong production test/QA methodologies.
