  • Develop RF front-end architectures including LNAs, filters, matching networks, RF switches, and timing circuits.
  • Optimize sensitivity, tracking performance, positioning accuracy, and interference immunity.
  • Support RTK, navigation, and timing solutions.
• Antenna Design & Integration
  • Design and integrate patch, helical, ceramic, chip, active, and passive GNSS antennas.
  • Perform antenna tuning, impedance matching, ground-plane optimization, and radiation pattern evaluation.
  • Support coexistence with cellular and other wireless technologies.
• RF Design & Validation
  • Design and analyze RF receiver circuits and subsystems.
  • Perform RF simulations and measurements using VNAs, spectrum analyzers, oscilloscopes, and signal generators.
  • Evaluate noise figure, gain, sensitivity, linearity, phase noise, and S-parameters.
  • Document verification and test results.
• Wireless Communications Support
  • Support RF transceiver design including LNAs, filters, mixers, synthesizers, and VCOs.
  • Contribute to cellular, Wi-Fi, Bluetooth, ISM-band, and proprietary radio solutions.
  • Evaluate GNSS and communications coexistence.
• Product Support & Leadership
  • Support manufacturing transfer and resolve production or field issues.
  • Lead root-cause investigations and sustaining engineering activities.
  • Provide technical guidance to technicians, designers, and junior engineers.
  • Evaluate emerging GNSS, RF, and wireless technologies.
