* Designing and developing BAW & SAW filters.* We need BAW filter designers (not RF active devices).* Perform advanced EM simulations using tools such as HFSS, ADS, or COMSOL to model BAW filter performance, optimize designs, and ensure manufacturability.* Design RF modules integrating BAW filters, including layout, packaging, and integration with other RF components such as amplifiers, switches, and antennas.* Optimize filter performance for key metrics such as insertion loss, return loss, bandwidth, and out-of-band rejection, while meeting size and cost constraints.* Work closely with process engineers, layout designers, and system architects to ensure seamless integration of BAW filters into larger RF systems.* Develop test plans, perform RF measurements, and validate filter performance using tools like network analyzers and spectrum analyzers.
* Bachelor's degree in engineering or STEM discipline.* 7+ years of experience in RF filter design with a focus on BAW or SAW.* Experience in EM simulation tools (e.g. HFSS, CST, ADS, or COMSOL).* Experience with RF measurement equipment. PREFERRED QUALIFICATIONS:* Experience with 5G, Wi-Fi, or IoT RF front-end module design.* Familiarity with MEMS fabrication processes for BAW filters.* Knowledge of mixed-signal design and co-simulation with analog/digital circuits.* Experience with scripting languages (e.g., Python, MATLAB) for automation of simulation and testing workflows.
