RFIC Design Engineer
Austin, Texas, United States
The wireless RFIC team architects, designs, and validates radio transceivers integrated into complex wireless SoCs. Our transceivers have powered wireless connectivity solutions for Apple wearable products, enabling the smallest form factor at the lowest power envelope. You will have the opportunity to do innovative development in transceiver design while working closely with systems and product teams at Apple. In this highly visible role, you will be at the center of a silicon design group with a critical impact on getting functional products to hundreds of millions of customers quickly. Positions are available for multiple experience levels.
- Direct experience designing and bringing into mass production RF transceivers in deep sub-micron RFCMOS technology. This includes design of on-chip LNAs and PAs as well as calibration methods associated with such high performance wireless systems and ZIF designs. Experience should also include understanding of DFT and DFM techniques for mass production environment.
- Deep understanding in system specification and ablility to work with system architects to translate system requirement into circuit requirement at IC level. Deep understanding of impact of modulation type to radio architecture and requirements.
- Familiarity with various RF transceiver architectures and their trade-offs; capability to work with digital design group for an optimum partition between digital and analog domain.
- Deep understanding of RF CMOS implementation fundamentals, and basic building blocks, including LNAs, mixers, VCOs and DCOs, LO and PAs.
- Deep understanding of RF device modeling, including device noise parameters and inductor modeling. Insights into packaging effects, supply isolations, high frequency ESD structures, and circuit layout for optimum RF performance.
- Deep understanding of device noise, mismatch, linearity, and other analog impairments.
- Strong knowledge of desense and able to work closely with board RF/HW/Antenna teams to optimize board layouts for desense mitigation. Experience with desense mitigation with integrated PMUs/DSPs (i.e. substrate isolation, return loops, package isolation, frequency planning, etc).
- Familiarity with mixed signal mode verification methodology.
- Solid experience in Si characterization and debug.
- Ability to drive strong production test/QA methodologies.
- Experience in IP sourcing and management.
As a RFIC design engineer, you will be responsible for providing RF solutions for wireless chips. Responsibilities include: - Work with platform architects, system and digital design groups to define the requirements for RF and baseband blocks based on the system requirement. - Work with technology team on process selection for the target device. - Transistor-level feasibility studies of RF/mixed-signal circuit blocks and architectures. - Design various component blocks inside radio including RF front-ends, baseband filters/VGAs, LO/PLL circuits, data converters, and power management circuits. - Provide guidance on RF analog issues across Apple.
