Description
You will be responsible for assessing platform-level multi-radio coexistence performance, including: - Performing HW failure analysis at the RF/wireless system level to understand low margin or failing behaviors making use of hands-on experimental modifications to hardware. - Proposing design and process changes for multi-radio coexistence issues considering design constraints and align with cross-functional partners on trade-offs and implementation path. - Reviewing designs and sign-off on releases of PCB layouts, flex layouts, system level groundings, shielding. - Execution of validation & characterization test plans to meet multi-radio coexistence performance targets. - Tracking validation status, analyze results and communicate insight from data. - Evaluating multi-functional change requests and update characterization plans as needed, highlight any issues. - Working with RF Test Engineers to bring-up device-under-test, setups and test procedures for multi-radio coexistence validation. - Performing simple experiments using hardware mock-ups, system prototypes and experimental setups. - Collaborating with cross-functional partners for circuit-level, system-level simulations to understand risk areas and root cause issues.
