Job description

FBAR Filter Designer

Lead end-to-end FBAR filter development from design to high-volume production

Location: San Jose, California

Compensation: $121,900 - 195,000 USD / year

About The Role

FBAR Filter Designer

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.

Key Responsibilities

• Design & Synthesis: Design high-Q FBAR filters and multiplexers using optimized topologies.
• Layout & Floor Planning: Own the physical die layout and package integration, optimizing for parasitics and thermal dissipation.
• Module Co-Design: Manage the interface between acoustic die, laminate, and PCB to ensure signal integrity and target performance.
• EM Co-Simulation: Lead 3D EM simulations to model package-level parasitics, interconnects, and coupling.
• Yield & Verification: Perform Monte Carlo and corner analyses to ensure robust performance for high-volume manufacturing (HVM).
• Collaboration: Partner with process, modeling, test, module, and other design teams to correlate simulations with measured lab data and drive design iterations.

Skills & Experience

• Acoustic/RF/Microwave Expertise: Deep understanding of FBAR/BAW/SAW physics or extensive experience in RFFE module integration and RF/microwave circuit theory.
• Simulation Mastery: Expert proficiency in ADS and 3D EM tools (e.g., HFSS, CST, or Sonnet).
• System Knowledge: Strong grasp of RFFE architectures, including carrier aggregation and coexistence specifications.
• Communication: Excellent verbal and written skills; ability to explain complex technical trade-offs to cross-functional teams and stakeholders.

Education & Qualifications

• 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.

Compensation and Benefits

The annual base salary range for this position is USD 121,900.00 To USD 195,000.00. As a valued member of our team, you'll be eligible for a discretionary annual bonus and the opportunity to receive not only a competitive new hire equity grant, but also annual equity awards, connecting your success directly to the company's growth. All subject to relevant plan documents and award agreements.

Broadcom offers a competitive and comprehensive benefits package: Medical, dental and vision plans, 401(K) participation including company matching, Employee Stock Purchase Program (ESPP), Employee Assistance Program (EAP), company paid holidays, paid sick leave and vacation time. The company follows all applicable laws for Paid Family Leave and other leaves of absence.
