Responsibilities
- Implement and test simple RF building blocks, including filters and couplers, from established schematics.
- Run directed simulations using Advanced Design System, High-Frequency Structure Simulator, and Computer Simulation Technology; document results and perform basic parameter sweeps.
- Execute bench measurements using vector network analyzers and spectrum analyzers; record first-order data.
- Support bill of materials creation and end-of-life data gathering.
- Collaborate with mechanical and software teams on interface details.
- Collect and organize test data, perform basic trend analysis, and prepare charts and summary reports under guidance.
- Iterate low-noise amplifier, power amplifier, and mixer front-end designs; address biasing, stability, and matching networks.
- Perform simulations, correlate models to measurements, and refine designs to meet gain, noise figure, and linearity requirements.
- Develop and execute test plans; interpret results to drive corrective actions.
- Partner with manufacturing on thin-film, printed circuit board, and box-build considerations; incorporate design-for-manufacturability and design-for-test feedback.
- Create accurate bills of materials with alternates and assist with end-of-life analysis.
- Analyze RF performance data, including gain, noise figure, and linearity, and correlate results with simulation outputs.
- Generate structured reports containing observations, root-cause hypotheses, and recommended corrective actions for review by senior engineers.
- Architect and lead subsystem designs, including up/down-converters, mixers, and synthesizers, while balancing gain, noise figure, linearity, spurious performance, and thermal stability.
- Own model-to-hardware correlation using electromagnetic/circuit co-simulation and statistical analyses.
- Direct rigorous validation using vector network analyzers, spectrum analyzers, and custom fixtures; interpret complex data.
- Lead manufacturability integration, manage new-product-introduction transitions, and evaluate reliability/yield tradeoffs.
- Perform end-of-life analysis, select replacements, and manage compliance impacts.
- Interpret complex RF test datasets and simulation results to validate subsystem performance.
- Prepare comprehensive technical reports for internal design reviews and customer review meetings.
- Mentor junior engineers and lead design reviews.
