FBAR Filter Designer - USA-California- San Jose - 1730 Fox Drive, United States
$121,900 - $195,000 USD yearly
Originally posted 14 September 2026 by the employer — open 4 days.
About the role
This role involves leading the development of high-performance RF Front-End (RFFE) solutions, owning the design lifecycle from acoustic resonator synthesis to full module integration.
What you'll do
- Design high-Q FBAR filters and multiplexers using optimized topologies.
- Own physical die layout and package integration, optimizing for parasitics and thermal dissipation.
- Manage the interface between acoustic die, laminate, and PCB to ensure signal integrity and target performance.
- Lead 3D EM simulations to model package-level parasitics, interconnects, and coupling.
- Perform Monte Carlo and corner analyses to ensure robust performance for high-volume manufacturing (HVM).
- Partner with process, modeling, test, module, and other design teams to correlate simulations with measured lab data and drive design iterations.
What you'll need
- Deep understanding of FBAR/BAW/SAW physics or extensive experience in RFFE module integration and RF/microwave circuit theory.
- Expert proficiency in ADS and 3D EM tools (e.g., HFSS, CST, or Sonnet).
- Strong grasp of RFFE architectures, including carrier aggregation and coexistence specifications.
- PhD (EE/Physics) with 3+ years experience OR Master’s with 7+ years experience in RF/Microwave design (Acoustic Filter or RFFE Module).
- Proven track record of successful tape-outs or high-volume product releases.
