RF Test Engineer

Roles & Responsibilities

• Develop RF test plans, test procedures, test matrices and acceptance criteria.
• Perform module, subsystem and system-level RF testing and characterization.
• Measure gain, insertion loss, return loss/VSWR, P1dB, IP3, noise figure, harmonics, spurious, isolation, phase noise and frequency accuracy.
• Test RF chains including T/R modules, PA, LNA, PLL/synthesizer, mixers, filters, switches, up/down converters and beamformers.
• Perform RF calibration, channel-to-channel amplitude/phase verification and RF path validation.
• Develop RF test setups and troubleshoot hardware, LO, clock, power and signal-chain issues.
• Support integration, qualification, ATP/QTP and production acceptance testing.
• Prepare test reports, failure analysis, requirement compliance and technical documentation.
• Coordinate with digital/FPGA, software, mechanical, system and production teams.
• Coordinate with PCB/layout engineers to ensure schematic-to-layout implementation complies with RF design and manufacturing requirements.
• Guide and review RF PCB layout and routing for controlled impedance, grounding, shielding, isolation, return-current paths, RF component placement and signal integrity.
• Create RF schematics in OrCAD Capture, including RF signal paths, bias networks, power distribution, control interfaces and test points.

Requirements

• Hands-on experience with VNA, spectrum/signal analyzer, RF signal generator, power meter and oscilloscope. OrCAD Capture schematic development and RF PCB layout review experience.
• Strong understanding of RF measurement techniques and RF component characterization.
• Experience in RF subsystem/radar testing and troubleshooting.
• Working knowledge of ADS, MATLAB or Python is desirable.
• Experience in radar, AESA, SAR, EW, satellite or other high-performance RF systems.
• Experience with T/R module and phased-array RF testing is preferred.
• Typical experience: 3-5 years in RF testing, RF characterization or RF system verification.
