Job Description

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

Masters 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.
