Conduct RF system acceptance testing and characterization using VNAs, spectrum analyzers, noise figure analyzers, and power metersDevelop and maintain link budget models and RF cascade analyses; identify margin risks before they become field problemsWrite test procedures, characterization reports, and RF performance documentationRequired Skills Hands-on experience with satellite communications terminal RF systemsStrong command of system-level RF metrics: G/T, noise temperature, EIRP, link budget, noise figure, fade marginProficient with RF bench instrumentation: VNA, spectrum analyzer, noise figure analyzer, power meter, signal generatorExperience selecting and sourcing LNAs, SSPAs, filters, diplexers, and coaxial/waveguide components for satcom applicationsDemonstrated ability to own a component BOM — from specification through procurementSome Working knowledge of DVB-S2 or other satellite waveforms and modem-level integrationField instinct: you're comfortable on a rooftop or a remote site, troubleshooting with limited resourcesDesired Skills Experience with parabolic dish antenna systems: feed installation and polarization alignmentFamiliarity with antenna control systems (ACUs, Az/El pedestals, drive electronics)Link budget modeling across LEO, MEO, and GEO orbit scenariosExperience commissioning or troubleshooting RF systems at remote or field sitesFamiliarity with low-noise amplifier noise performance characterizationIn order to comply with the space technology export rules of the U.S. Government, such as the International Traffic in Arms Regulations (ITAR), it is necessary to be a U.S. citizen, a lawful U.S. permanent resident, a protected individual as specified by 8 U.S.C. 1324b(a)(3), or possess eligibility to secure the necessary authorizations from the U.S. Department of State. Responsibilities Characterize and optimize RF system performance for satellite communications terminals: G/T, noise temperature, EIRP, link margin, noise figure across S-band, X-band, and beyondDefine, select, and manage RF front-end components and BOMs for terminal hardware — LNAs, SSPAs, feeds, diplexers, cables, connectors, and waveguide componentsTroubleshoot RF system issues across the full receive and transmit chain, from the antenna feed through to the modemDrive integration of next-generation modem hardware into RF terminal systems; validate waveform and link performanceWork with antenna and mechanical teams to ensure RF system requirements are met through pointing accuracy, feed alignment, etc.
