Description
In this role, you will be part of an industrial-leading RF Transmitter Systems Engineering team. You will work closely with other architecture- and systems engineering teams, RF design teams and SW teams to assess, specify and drive transmitter concepts with focus on leading-edge performance and uncompromised quality as baseline for differentiating products. Your daily work includes the following tasks.","responsibilities":"Translate PHY and RF system-level performance requirements into requirements for the TX line-up and features, including RF control/algorithm specifications for RFICs and system firmware.
Understand and specify RF algorithms (e.g. power control, calibration) and define the RF control infrastructure, including compute resources, interfaces, memory and timing constraints.
Lead HW/SW partitioning of RF algorithms (control functionality), ensuring optimal trade-offs between flexibility, latency and power.
Run simulations (e.g., MATLAB, Python, C) for performance analysis and PHY collaboration.
Identify and analyze critical requirements and provide deep-dive assessments of system performance impact, timelines and risks.
Drive the alignment of requirements, design targets and design trade-offs with other teams such as HW design and SW engineering.
Provide specifications as input for the HW and SW development.
Preferred Qualifications
5+ years of relevant experience in RF, including cellular transmit architectures, or PhD degree with previous work on cellular topics.
