Apple GNSS RF System Architect United States, California, Sunnyvale 112047651
07.04.2025
Translate system level GNSS receiver requirements into detailed specifications for the antenna, RF front end, and integrated RX chain (including the breakdown to block / component level). Run static analysis for specific scenarios defined for the product by the architecture teams. Select, simulate and specify RF architectures suitable for integration into a GNSS receiver SoC. Drive the further development of the simulation environment and modeling. Prepare specifications as input for RFIC design team and FW team. Analyze the receiver chain by means of simulations in MATLAB, and level plan / impairment analysis (SysCalc). Identify and analyze critical requirements, and provide assessments with respect to critical metric impact, timeline and risks. Solve sophisticated and interdisciplinary problems that are related to the GNSS receive system. Support RF SiVal in defining and carrying out measurements to validate RX performance. Assist with silicon debug, and propose solutions and workarounds as needed.
- Minimum requirement of BS and 3+ years of relevant industry experience.
- 3+ years experience in RF Systems performance criteria and concepts such as AGC, noise figure, sensitivity/de-Sense, phase noise, spurious responses, harmonics and intermodulation.
- Strong analytical and interpersonal skills with an ability to thrive in a multi-functional environment.
- Excellent verbal and written communication skills.
- MSEE or beyond is preferred.
- 4+ years of proven experience in RF, including receiver system architecture design, with emphasis on integrated SoC solutions
- Expertise in RF System concepts and procedures for wireless systems including calibrations, analysis of receiver chains from RF antenna to digital baseband IQ, and translating top-level requirements into specification items for transceiver building blocks and RF components (e.g. LNA, Mixer, PLL, ADC, and Filters).
- Familiarity with Receiver Digital Signal Processing blocks (e.g. decimation, filtering, resampling, IQ correction, etc)
- In-depth knowledge of wireless radio standards (Connectivity, Cellular or GNSS), including their implications on system specifications.
