Job description

Open for Candidates located in the US, Canada, and Europe

Builds on 30-year legacy of technology advancements and strong IP portfolio but with a new mission— to enhance world-class capabilities with high-performance semiconductors. With a strong foundation in RF integration, their 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, team explores new ways to make electronics for the connected world smaller, thinner, faster, and better

Individual will be responsible for the design validation, characterization & product development of RF and mixed signal ICs in UltraCMOS technology for mobile wireless RF front end semiconductor products for cellular handsets and commercial/industrial applications. A successful candidate will enjoy being part of the product development team, demonstrating leadership in taking industry-leading product designs to mass production.  Product lines include high performance RF switches, PA controllers (PAC’s), power amplifiers, low noise amplifiers, digital tunable capacitors, couplers, and IC filters.

The job will require expertise in RF and analog measurements combined with disciplined project planning to ensure only the highest quality products are released. As part of a cross-functional product development team, the candidate will support other essential disciplines including marketing and applications, project management, design, production, and test engineering.  The candidate will work very closely with the design team to understand the part operation and device. This position will be in Arlington Heights, IL office

  • Product Evaluation: Perform lab measurements on various RF/mixed signal front end IC’s (LNA, SW, PA, PAC’s, Couplers, Digital tunable capacitors, and IC filters) and create design validation report with comparisons vs design expectations.
  • Product Characterization: Perform product characterization over a superset of conditions specified in the datasheet. Drive the development of necessary benches to evaluate all relevant performance requirements.
  • Product Qualification: Analyze results from products being stressed for lifetime reliability.  Support bench testing of qualification units when necessary.
  • Product Documentation: Document all relevant product information specific to the performance and limitations of the device as future reference for application and customer support.  Provide data sheet performance limits based on design verification and characterization data.
  • Production ATE Development: Work with Test Engineers to create a correlation between bench measurements ATE solution.
  • Analysis Tool Development: Develop characterization and test data analysis tools to streamline characterization (CPK analysis) and improve ATE capability understanding (GR&R).
  • 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.
  • Mentor members of the team to develop their technical skills
