NorthwoodSpace Senior RF Electrical Engineer owns Ka-band high power amplifier design from architecture through production for Northwood's Prism antenna. The role includes designing, simulating, characterizing, and driving amplifier designs through reliability testing and production.

Responsibilities

Design Ka-band high power amplifiers for Prism, 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 (amplifier stages, matching networks, combiners, transitions) 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 in partnership with mechanical and thermal engineers
Characterize amplifier performance (output power, compression, PAE, linearity, spurious, stability) 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

Qualification

Comfort with RF test equipmentGaN MMIC-based amplifier designPower combiner designSatcom transmit compliance

Required

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

Preferred

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
