Key Responsibilities:
  • Design, simulate, and validate RF communication systems for lunar rover communications, focusing on antenna patterns, radiated fields, and microwave circuits
  • Perform advanced electromagnetic simulations to analyze multipath effects, Rician fading, and other propagation phenomena in lunar environments
  • Optimize impedance matching and develop Smith charts to ensure efficient RF performance
  • Develop and refine channel models to account for the unique propagation challenges on the lunar surface
  • Collaborate with the DSP team to integrate RF subsystems with digital signal processing techniques, ensuring seamless communication and optimal error vector magnitude (EVM)
  • Design and evaluate microwave circuits and systems for efficient transmission and reception of digital and analog signals
  • Analyze and mitigate RF interference and develop strategies to improve communication robustness
  • Collaborate closely with other engineering teams to ensure RF systems are compatible with overall rover systems, including power, thermal, and structural subsystems
  • Support testing, verification, and validation efforts for the rover's communication system, both in lab environments and in mission simulations
Requirements:
  • Bachelor's degree in Electrical Engineering, Telecommunications, or related field. Master's or PhD preferred
  • 7+ years of experience in RF engineering, with a focus on high-frequency, space-based, or aerospace communication systems
  • Strong expertise in RF simulations, antenna design, and analyzing radiated fields
  • Proficiency with RF simulation software such as HFSS, CST, or COMSOL
  • In-depth knowledge of impedance matching, Smith charts, S-parameters, and RF front-end design
  • Experience with channel modeling, particularly in multipath environments and under Rician fading conditions
  • Expertise in high-frequency microwave circuit design, testing, and optimization
  • Strong understanding of DSP principles as applied to RF communication systems
  • Familiarity with RF test equipment, including network analyzers, spectrum analyzers, and signal generators
  • Demonstrated experience with space communication standards and working with cross-functional teams in aerospace or high-tech environments
Preferred Skills:
  • Experience working with lunar or planetary exploration missions
  • Familiarity with radiation-hardened RF design
  • Experience with rover or satellite communication systems
  • Familiarity with terrestrial mobile communication standards and designs, such as 3GPP
