RF Package/IC Tester

Job Summary

We are seeking a highly skilled RF Tester with a minimum of 5-10 years of relevant experience to execute comprehensive testing of RF IC packages in various form factors, primarily LGA. The ideal candidate possesses a deep understanding of RF testing methodologies and a proven track record in 5G RF testing. This role requires a strong technical foundation, excellent problem-solving abilities, and a collaborative team orientation.

Responsibilities

  • Develop and execute test plans, including test strategy definition, tester configuration, socket selection, and validation for RF IC packages, including small signal, power amplifier, and mmWave components.
  • Perform in-depth characterization of RF devices, measuring parameters such as gain, noise figure, linearity (IIP3, OIP3, OP1dB), EVM, settling time, and spurious response.
  • Conduct bias controller tests involving ADC and DAC characterization.
  • Execute reliability testing as required.
  • Support bench to ATE correlation.
  • Analyze test data, identify anomalies, and collaborate with engineering teams to resolve issues.
  • Maintain accurate and detailed test documentation.
  • Stay up-to-date with the latest RF testing technologies and industry standards.
  • Travel to international sites, such as Taiwan, for project support as needed.
  • Collaborate closely with design engineering to optimize product testability and manufacturability.
  • Drive ATE bring-up, optimization, and production ramp-up, adhering to industry best practices and GRR methodologies.
  • Optimization of hander settings for best RF performance
  • Analyze test data to identify process improvements, yield enhancement opportunities, and cost reduction strategies.
  • Mentor and develop team members, fostering a culture of technical excellence and innovation.

Qualifications

  • Master's or Ph.D. in Electrical Engineering or a related field.
  • Minimum of 5-10 years of hands-on experience in RF testing.
  • Proficiency in RF test equipment and software (e.g., network analyzers, spectrum analyzers, power meters, oscilloscopes).
  • Strong programming proficiency (C++, Python, Matlab, Perl) and in-depth understanding of ATE testing methodologies.
  • Strong understanding of RF circuit theory and measurement techniques.
  • In-depth knowledge of RF testing standards and methodologies.
  • Experience with 5G RF testing is highly preferred.
  • Proficiency in data analysis and statistical process control (SPC).
  • Excellent problem-solving, analytical, and troubleshooting skills.
  • Strong attention to detail and accuracy.
  • Excellent communication and interpersonal skills.
  • Ability to work effectively in a team environment.
  • Willingness to travel domestically and internationally.

Technical Skills

  • Hands-on experience in small signal testing (LNA, LNA+SW) at 8GHz, including parameters like gain, noise figure, two-tone IIP3, OIP3, OP1dB, EVM, and settling time.
  • Expertise in noise figure testing with 0.05dB accuracy.
  • Experience in small signal pre-driver testing, including OIP3 measurement.
  • Proficiency in mmWave LNA testing (gain, NF, OP1dB, OIP3, NF 1-2dB).
  • Knowledge of mmWave up-down converter testing (gain, NF, OIPdB, OIP3, spurious response) within the 15-35 GHz frequency range.
  • Experience in mmWave beamformer transceiver testing (gain, phase, efuse, gain, NF, OP1dB, OIP3, EVM).
  • Expertise in 8GHz power amplifier testing, including bias sequencing, leakage currents, quiescent currents, AM2PM, pulsed-CW with 5% duty cycle in pulse RF, and modulated tests (average gain, efficiency, ACLR).
  • RF theory and application, ATE systems, test program development, data analysis, project management, statistical process control (SPC), and yield improvement.

Desired Qualifications

  • Experience with reliability testing methods.
  • Knowledge of scripting languages (e.g., Python, MATLAB) for test automation.
  • Experience with statistical data analysis tools.
