  • Creation of custom electrical models of passive package parasitics and matching components such as alumina substrates, bondwire arrays, and high dielectric matching capacitors using industry standard 2.5D MoM and 3D FEM simulators.
  • Device testing and characterization including s-parameter, large signal, load-pull, stability over temperature and VSWR, as well as market specific measurements on a per-product basis such as modulated signal measurements.
  • Multistage circuit design and layouts based on existing designs 

What you need for success:

  • B.S.E.E. or equivalent experience
  • 5 years microwave circuit design experience with at least 3 years on GaAs or GaN hybrid and MMIC power amplifiers
  • Working experience with industry standard non-linear circuit simulators ADS and MWO and electromagnetic modeling software (e.g. HFSS or equivalent)
  • Working experience with microwave test equipment (e.g. Agilent VNAs) and standard device characterization/de-embedding techniques
  • Demonstrated ability to work within schedule constraints
  • Excellent communication and team skills
  • US Citizen or green card holder 

 Highly preferred skills and certifications:

  • M.S.E.E. or equivalent experience
  • 7 years microwave circuit design experience with at least 5 years on GaAs or GaN hybrid and MMIC power amplifiers
  • Experienced user of AWR and ADS non-linear circuit simulators
  • Experienced user of Axiem and HFSS electromagnetic modeling software
  • Experienced user of microwave test equipment
  • Experience with standard device characterization/de-embedding techniques
