Our RF Systems Engineering team is looking for a passionate, self-motivated individual to work on overall system performance of multi-radio coexistence for various wireless technologies (Cellular, Wi-Fi, BT, GPS, NFC, etc.).
Key Qualifications
- Hands-on experience with two or more Cellular, GPS, Bluetooth / Thread, Wi-Fi, NFC, UWB radios; or one radio with both conducted and radiated experience
- Hands-on experience in system level debug, optimization and mitigation strategies on at least one of: conducted, radiated multi-radio coexistence, radiated emission or radiated desense
- Experience of wireless architecture design for simultaneous multi-radio operation requiring filtering, linearity requirements, and mitigation strategies
- Demonstrated knowledge of RF hardware and system design considerations of system-level grounding, shielding, isolation, and electromagnetic interference mitigation
- Proven understanding on RF link budget, Rx gain line-up, Rx AGC operation and optimization techniques in the presence of different jammer conditions
- Hands-on experience in system level debug and making experimental modifications to intricate hardware on small form factor consumer electronics including wearables, phones, and pads
- Excellent understanding of RF component characteristic and have experience using lab equipment including spectrum analyzer, network analyzer, signal generator, oscilloscope, and/or packet sniffer
- Knowledge of MAC/PHY and throughput performance
- Excellent written and verbal communication skills
- Ability to travel domestically and internationally up to 20%
Description
You will be responsible for wireless systems aspects of wireless multi-radio coexistence performance in consumer products, including:
- Performing feasibility investigation on new technologies, RF features, test methodologies, components, strategies and processes working with cross-functional partners, component vendors and technology suppliers
- Proposing design and process changes for sophisticated multi-radio coexistence issues considering trade-offs and implementation constraints
- Collaborating on developing system mitigations that optimizes product performance across hardware, firmware, software and algorithms
- Defining test plans and methodologies to meet multi-radio coexistence performance requirements aligned cross-functionally
- Defining sophisticated experiments using modified development hardware, experimental setups, circuit and system-level simulations to understand risk areas and root cause issues
- Translating system level requirements to sub-system, module, component and chipset level requirements working with chipset and system partners
- Working closely with RF hardware engineers and RF test engineers, tracking validation progress, bringing insight into data, and presenting to senior management
- Influencing multi-radio coexistence product integration decisions
Education & Experience
BS with 10+ years relevant experience required. MS/PHD preferred.
