Senior RF Electrical Engineer, Amplifiers (Prism)
Torrance, CA. Posted 16 days ago
The role
You will own Ka-band high power amplifier design for Prism, a 2.4-meter parabolic antenna. You will take amplifiers from architecture through prototype, characterization, and production.
What you will do
- Design Ka-band high power amplifiers from line-up and architecture through schematic, layout, and hardware bring-up
- Develop power combining approaches that scale output power while protecting efficiency, linearity, and reliability
- Build electromagnetic and circuit simulation models to design and evaluate performance before hardware
- Design supporting circuitry, including bias and sequencing, power conditioning, protection, monitoring, and digital control interfaces
- Own thermal and packaging considerations for high-dissipation RF hardware
- Characterize amplifier performance and troubleshoot integrated transmit chain performance
- Drive designs through reliability testing and into production, including test definition and manufacturing support
- Support integration and field troubleshooting of deployed Prism units
Required qualifications
- Bachelor's degree in electrical engineering or a related engineering discipline
- 5+ years of RF hardware design experience
- Hands-on experience designing and building power amplifiers at microwave or millimeter-wave frequencies (Ku-band or higher)
- Experience taking RF hardware from design through bring-up, characterization, and debug in the lab
- Proficiency with RF and EM simulation tools (such as Keysight ADS, Cadence AWR, Ansys HFSS, or CST)
- Comfort with RF test equipment, including network analyzers, spectrum analyzers, signal generators, and power meters
Nice to have
- Master's degree or PhD in electrical engineering with a focus on RF or microwave design
- Ka-band solid state power amplifier (SSPA) or block upconverter (BUC) design for satellite communications
- GaN MMIC-based amplifier design, including device selection, matching, stability analysis, and bias networks
- Power combiner design, including waveguide, spatial, or planar approaches
- Waveguide component and transition design, including waveguide-to-microstrip transitions, rotary joints, and feeds
- Thermal management and packaging for high power RF electronics
- Linearity and modulated signal performance (IMD, ACPR, EVM, spectral regrowth), including linearization techniques
- Satcom transmit compliance, including emission masks and regulatory limits
- Design for manufacturing, production test development, and reliability qualification
Before you apply
- To conform to U.S. Government space technology export regulations, including the International Traffic in Arms Regulations (ITAR) you must be a U.S. citizen, lawful permanent resident of the U.S., pro
