The RF characterization engineer will deliver Front-End Module design validations in a fast-paced team environment, and will work closely with RF IC design engineers to optimize a design by extensive data collection, analyzing the data and co-designing the product based on RF system knowledge.

Main responsibilities

  • Design and develop engineering evaluation test boards for RFFE products
  • Develop characterization test plans to report the performance of RFFE products in a highly automated RF test environment
  • Work with LNA test setup such as PNAX, PXA, network analyzers, noise figure measurement, sophisticated ET/DPD system tools, system alignment, transceiver optimization as well as antenna tuners to optimize the performance
  • Characterization reporting includes all the parametric data from RF Front End such as Rx path NF, noise circles, IP2/IM2, IP3/IM3, Gain modes, S-parameters of Rx path components, as well as Tx path PAE, Gain, ACLR, power sweep, Rx Band Noise, Spectrum Emission Mask, s-par, x-par, Load-pull, Out-of-band rejection and frequency sweeps amongst others. Collect and evaluate data to verify performance over temperature, voltage, and process corners.
  • Summarize and create performance reports, improve report automation
  • Select, implement, and maintain test equipment necessary for RFFE product characterization. Work with IC design team to maintain, optimize, and release chip setting for overall optimized product performances.
