FBAR Filter Designer

Broadcom•San Jose, CA

4d•$120,000 - $192,000

About The Position

We are seeking an FBAR Filter Designer to lead the development of high-performance RF Front-End (RFFE) solutions. You will own the design lifecycle—from acoustic resonator synthesis to full module integration—bridging the gap between die-level physics and system-level hardware for 5G and Wi-Fi standards.

Requirements

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.
Excellent verbal and written skills; ability to explain complex technical trade-offs to cross-functional teams and stakeholders.
PhD (EE/Physics) with 7+ years experience OR Master’s with 10+ years experience in RF/Microwave design (Acoustic Filter or RFFE Module).
Proven track record of successful tape-outs or high-volume product releases.

Responsibilities

Design high-Q FBAR filters and multiplexers using optimized topologies.
Own the 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.
