RF Design Engineer

Responsibilities

• Design, simulate, prototype, and test RF and microwave circuits operating from approximately 30 MHz to 6 GHz, including power amplifiers, low-noise amplifiers, filters, matching networks, and related components
• Develop and optimize RF power-amplifier designs with output-power levels generally ranging from 20 to 100 watts
• Design and evaluate broadband impedance-matching structures, transformers, baluns, combiners, filters, and custom magnetic components where applicable
• Perform RF circuit and electromagnetic simulation using Keysight ADS, AWR, HFSS, or comparable engineering tools
• Create and review schematics, component placement, controlled-impedance routing, grounding, shielding, and other RF-sensitive PCB layout features using Altium Designer or comparable ECAD software
• Conduct hands-on prototype assembly, modification, tuning, and troubleshooting using VNAs, spectrum analyzers, signal generators, oscilloscopes, power meters, and related laboratory equipment
• Evaluate gain, efficiency, linearity, harmonics, spurious response, stability, thermal performance, and tolerance to load mismatch where applicable
• Use measured data to identify design deficiencies, develop technical hypotheses, conduct controlled experiments, and implement design improvements
• Collaborate with mechanical, electrical, embedded-software, manufacturing, and test personnel to integrate RF designs into complete systems
• Support the design and integration of DC power supplies, bias circuits, protection circuits, thermal-management features, and embedded control functions for RF subsystems
• Produce clear design documentation, analyses, test results, design-review materials, and engineering change information
• Support design transfer, production troubleshooting, component substitutions, and continuous improvement of released RF products
