What you will do

• Architect wideband transmitter and receiver topologies, including superheterodyne, direct conversion, and direct RF synthesis or sampling, through Ka-band.
• Select high-speed DACs and ADCs and analyze dynamic range, bandwidth, SFDR, power, clock trees, phase noise, and aperture jitter.
• Design RF circuits, perform cascade analysis, develop schematics, and define high-frequency PWB layout constraints.
• Collaborate with hardware engineering on mixed-signal PWA implementation and noise-sensitive RF and analog power regulation.
• Work with mechanical engineering on shielding cavities, thermal management, and packaging.
• Conduct laboratory integration, tuning, and characterization using VNAs, spectrum analyzers, and signal generators.

Requirements

• B.S. or M.S. in Electrical Engineering, or equivalent experience.
• 10+ years of practical RF circuit and module development experience through Ka-band or millimeter-wave frequencies.
• Expertise in RF transceiver architectures, direct RF synthesis, clocking architectures, frequency plans, and reference oscillator selection.
• Experience with phase noise, aperture jitter, clock purity, high-frequency PWB layout, stack-up definition, and supplier technical management.
• Proficiency with Keysight ADS, HFSS, Microwave Office, MATLAB, and millimeter-wave test equipment calibration and debugging.
• US citizenship and the ability to obtain and maintain a United States Secret Clearance are required. Familiarity with AI tools for technical analysis, scripting, and workflow optimization is expected.

Nice to have

• Experience with phased-array architectures, corporate feed and distribution networks, or phased-array testbeds.
• Knowledge of JESD204B/C routing, clock distribution, power-supply noise rejection, environmental qualification, and EMI/EMC.

Culture & Benefits
