Senior RF Engineer - Transceiver Module at Viasat | LAYIQ

Architecture & Signal Path Design: Architect wideband transmitter and receiver topologies (superheterodyne, direct conversion, and direct RF synthesis/sampling) and frequency conversion assemblies operating up through Ka-band.
Converter & Clocking Analysis: Select high-speed DACs and ADCs based on dynamic range, bandwidth, SFDR, and power constraints. Evaluate system clock trees, phase noise, and aperture jitter to quantify direct impacts on converter performance.
Circuitry, Layout & Manufacturing: Perform detailed RF circuit design and cascade analysis (gain, noise figure, IP3, phase noise, spurs). Translate transceiver architectures into schematics, define critical high-frequency layout constraints, and interface directly with fabrication and assembly partners.
Cross-Disciplinary Execution & Test: Partner with Hardware Engineering on PWA implementation and power regulation for noise-sensitive RF/analog paths, and with Mechanical Engineering on shielding cavities, thermal management, and packaging. Conduct laboratory integration, tuning, and characterization using VNAs, spectrum analyzers, and signal generators.

B.S. or M.S. in Electrical Engineering (or equivalent experience)
10+ years of practical RF circuit and module development experience up through Ka-band/millimeter-wave frequencies.
Technical proficiency in RF XCVR architectures, direct RF synthesis topologies, clocking architectures, frequency plans, and primary reference oscillator selection.
Expertise in analyzing phase noise, aperture jitter, and clock purity to assess effects on converter performance.
Expertise with schematic development, high-frequency PWB layout routing, stack-up definition, and supplier technical management.
Proficiency with RF simulation software (Keysight ADS, HFSS, Microwave Office, MATLAB) and millimeter-wave test equipment calibration and debug.
Technical understanding of high-speed digital board design concepts and mixed-signal interface principles.
Willingness to use AI tools as interactive partners for technical analysis, scripting, and workflow optimization.
US Citizenship Required
Ability to Obtain and Maintain Secret Clearance.
