RF and YIG Design Engineer - US-CA-Santa Rosa-Bldg 4, United States
$124,420 - $207,370 USD yearly
Originally posted 26 June 2026 by the employer.
Design YIG filters, oscillators, and high-current driver circuits within Keysight Laboratories.
About the role
As an R&D RF and YIG Design Engineer at Keysight Laboratories, you will design, validate, and implement high-performance microwave/mm-wave and frequency synthesis solutions. The role focuses on advancing YIG-based components, electromagnetic modeling, magnetics, and system-level integration.
What you'll do
- Design and develop YIG-based components and subassemblies, including YIG filters and oscillators. - Determine and develop approaches across end-to-end product development, from concept and simulation through prototyping, testing, and production. - Apply multi-physics principles and simulations to optimize performance and reliability. - Perform RF/microwave analysis and validation, including S-parameter characterization and phase noise evaluation. - Design and implement high-current driver circuits for YIG devices. - Provide technical leadership by guiding architecture decisions, reviewing design approaches, and supporting design transitions into manufacturing.
What you'll need
- BS, MS, or PhD in Electrical Engineering or Physics, or equivalent, with a minimum of 8+ years of relevant experience. - Strong knowledge of RF and microwave theory, including S-parameters, filter theory, active microwave circuits, and RF building blocks. - Hands-on experience with RF measurement equipment, such as network analyzers, and spectrum and signal analyzers. - Proficiency with RF/microwave simulation tools, including both circuit and full-wave EM tools (e.g., ADS, EMPro, CST, HFSS, COMSOL). - Strong understanding of magnetics, including electromagnets, magnetic circuits, and hysteresis effects. - Demonstrated ability to lead complex technical investigations and make data-driven trade-off decisions.
Nice to have
- Experience with advanced electromagnetic and magnetic simulations, including transient behavior, loss mechanisms (hysteresis, eddy currents). - Solid experience in discrete circuit design, particularly high-current driver circuits. - Background in filter and/or oscillator design, and experience with low phase noise design and optimization. - Knowledge of material science, particularly crystalline structures, magnetic materials, and steel alloys. - Familiarity with PCB design tools (e.g., Mentor, KiCad) and phase-locked loop (PLL) design and applications. - Programming experience in C# or Python.
