Senior RF Subsystems Engineer position at Raytheon in Tucson, AZ. Responsible for designing, testing, and integrating RF sensors and subsystems across frequencies. Requires a degree in STEM and a minimum of 5 years of experience.
Requirements
- Design, test, and integrate RF sensors and subsystems across frequencies from MHz through millimeter-wave.
- Support the decomposition of system-level requirements into detailed RF component requirements.
- Measure RF components/sensors/subsystems, including performance in chamber and range environments.
- Perform modeling and analysis of link budgets, RF cascades, electromagnetic emissions (EME), antenna patterns, phase noise, receiver sensitivity, transmitter power, spurious signals, modulation, isolation, and ADC characteristics.
- Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 5 years of prior relevant experience unless prohibited by local laws/regulations.
- A minimum of 5 years of experience to include any combination of the following: Design, integration, and/or test of RF subsystems; Design, integration, and/or test of RF sensors; Experience interacting across engineering disciplines to define RF subsystem requirements and evaluate performance.
- Knowledge of RF component technologies, including circuit card assemblies (CCAs), waveguides, planar/printed antennas, RF modules, and/or monolithic microwave integrated circuits (MMICs).
- Experience performing Link Budget analyses.
- Understanding of antenna patterns and RF measurements with antennas and electronics.
- Experience in concepts such as phase noise, mixer conversion spurs, automatic gain control (AGC), sensitivity, intermodulation distortion (IMD), bit error rate, instantaneous bandwidth, adjacent channel interference, and ADC measurements/calculations (Nyquist and SFDR).
- Familiarity with equipment such as Spectrum Analyzers, Network Analyzers, Signal Generators, and Arbitrary Waveform Generators (ARB Generators).
- Understanding of electromagnetic interference (EMI) and electromagnetic vulnerability (EMV) along with mitigation strategies in RF systems.
- Excellent written communication and oral presentation skills.
