Job Description:

Select how often (in days) to receive an alert:pSemi Corporation is a Murata company driving semiconductor integration. pSemi builds on Peregrine Semiconductor's 30-year legacy of technology advancements and strong IP portfolio but with a new mission-to enhance Murata's world-class capabilities with high-performance semiconductors. With a strong foundation in RF integration, pSemi's product portfolio now spans power management, connected sensors, optical transceivers, antenna tuning and RF frontends. These intelligent and efficient semiconductors enable advanced modules for smartphones, base stations, personal computers, electric vehicles, data centers, IoT devices and healthcare. From headquarters in San Diego and offices around the world, pSemi's team explores new ways to make electronics for the connected world smaller, thinner, faster and better.Job SummaryThe Staff Characterization Engineer is responsible for validating leading edge RF Integrated Circuits, developing measurement systems of RFICs for mobile wireless and commercial/industrial applications; focusing on test solutions for mobile RF Front End ICs such as RF switches, LNAs, and Power Amplifiers. The job requires expertise in RF and analog measurements to ensure that pSemi's projects are accurately characterized prior to release, combined with disciplined project planning to ensure that schedules are met. The Staff Characterization Engineer will be expected to manage the project schedules, generate system specifications and create effective measurement solutions.Roles & ResponsibilitiesThis position has responsibility for:

• Characterization: Work closely with product designers to develop, evaluate and maintain optimum characterization plans for new product development. In addition to the characterization process, these include standards for conditions, quantities and in-process QA criteria as a function of parameter types.
• Data Analysis Standards: Develop, evaluate and maintain data analysis standards covering: statistical limit setting (including methods for aggregating statistics), yield prediction tools (Cpk analysis), tools and formats as a function of the parameter type.
• Characterization Infrastructure: Design and development of software and hardware for design validation, performance optimization, characterization and production test of RFICs. Analysis and development of optimization techniques for rapid characterization and test.
• Analysis Tool Development: Develop characterization and test data analysis tools to streamline characterization (CPK analysis) and improve ATE capability understanding (GR&R).
• Status Reporting: Be a technical leader through strong example and training of more junior engineers and provide continuous status updates to upper management and stakeholders.Minimum Qualifications (Experience and Skills)
• Typically requires 6 to 8 years of relevant experience depending on education level and experience.
• Ability to analyze RF systems for accurate measurement of large signal RF Front ends.
• Proficient in schematic capture, RF system integration and PCB design experience.
• Detailed knowledge of the following components: RF switches, PAs, LNAs, PLLs, Mixers and filters.
• Proficiency in software tools such as ADS and software for test development (Matlab, C#, LabVIEW, Python, NI TestStand).
• Expert in the analysis, troubleshooting and investigating RF related issues on systems and PCB assemblies.
• Familiarity with Vector Network Analyzers, Spectrum Analyzers, Signal Generators and Power Meters.
• RF Test Experience: Gain; S-Parameter; P1dB; IP2/IP3; Phase Noise; Noise Figure.
• Experience with automating lab instruments and optimizing measurements for speed.
• Knowledge of analog and RF IC design for commercial applications in bulk and/or SOI CMOS technologies.
• Knowledge of system level aspects of modern cellular handsets and networks.
• Cooperative team member with demonstrated out-of-the-box thinking and driving tasks to completion.
• Fundamental understanding of non-linear measurements and system noise performance.Preferred Qualifications
• Familiarity with RFFE MIPI, I2C and SPI digital interfaces.
• Familiarity with mmWave 5G Technology.
• Blind phase acquisition techniques.
• DSP.Education RequirementsBS Electrical Engineering, Computer Engineering or Equivalent; MSEE preferred.Work EnvironmentThis job operates on the Manufacturing Floor.
