About the role
- Our PA technology sits at the heart of a system-level approach to dramatically cutting base station power consumption, and this role puts you on the critical path from concept through volume production.
- This full-time position is based in San Diego, CA.
Responsibilities
- Develop ultra-high-efficiency RF power amplifiers (PAs) for 5G FR1 base station solutions
- Evaluate and adapt the use of available transistors and amplifiers for the design of these PAs in various (Gan, GaAs, LDMOS) technologies as applicable
- Design, simulate, and debug/evaluate RF PAs, presenting results to peers and stakeholders throughout the design cycle
- As simulation is imperfect, extract relevant empirical data to hone in on design targets
- Partner with Systems, RF/Analog, Digital, and Firmware engineers to deliver a complete base station solution
- Own RF PA designs through volume production, resolving issues that surface along the way
- Six or more years of direct, hands-on RF discrete PA design experience
- Proven experience across the full high-efficiency PA development cycle: device selection, evaluation and modeling, circuit design, linear and nonlinear simulation, PCB layout and parasitic extraction (EM analysis), and lab debug/bring-up/performance optimization
- Design experience spanning 0.5 MHz-6 GHz, with a solid understanding of higher-frequency effects
Requirements
- Working knowledge of efficiency-enhancement PA architectures such as (multi-level) Doherty, outphasing, active load modulation, and envelope restoration
Nice to have
- Working knowledge of transmitter linearization algorithms and their capabilities
- Broad exposure to RF passive (distributed) structures
- Sharp understanding of the relationships between CW and modulated device operation and performance
- Familiarity with RF PA-specific mechanical and thermal management approaches
- Experience with foundry model/PDK installation and use
- Interest in or experience with AI-assisted test data analysis and ML-based signal/power integrity prediction tools to catch issues earlier in the design cycle
- BSEE required, MSEE or PhD preferred
