RFIC Design Engineer

Job Overview:

We are seeking a highly skilled and experienced GaN Power Amplifier Designer to lead the research and development of a new ultra-efficient MMIC power amplifier product line. This role involves working with state-of-the-art GaN processes and requires expertise in RF/microwave integrated circuit design. The ideal candidate will have a strong background in RFIC design, hands-on experience with simulation tools, and a proven track record of delivering GaN power amplifiers into volume production. This is an onsite position located in Atlanta, Georgia, with relocation and sponsorship options available.

Responsibilities:

• Lead the research and development of a new ultra-efficient MMIC power amplifier product line in state-of-the-art GaN processes.
• Derive specifications for the MMIC subsystems and circuits.
• Design transistors, MMICs, passive devices, and other on-chip matching networks using state-of-the-art simulation tools.
• Model package and external parasitic components.
• Evaluate and characterize prototypes of the design.

Qualifications:

• PhD or Master's degree in Electrical Engineering or a related field, with an educational emphasis on RF/microwave integrated circuits design.
• 5+ years of proven experience in RFIC design and development, including specific experience designing power amplifiers (PAs) in GaN technologies.
• Demonstrated experience in end-to-end GaN power amplifier design, from initial concept and schematic design through layout, validation, and production release. Must have successfully designed and delivered at least one GaN PA that has been shipped in volume production.
• Strong circuit design skills and experience performing analysis and simulation of both linear and non-linear circuits for power amplifiers and other related RF circuit blocks like LNAs and switches.
• Proficiency in simulation and design tools such as Cadence (Virtuoso), Agilent ADS, Mentor tools, HFSS, or Keysight PathWave Design Suite (ADS, SystemVue, GoldenGate, Momentum, Spectre).

Preferred Skills:

• RF/microwave design experience in the GSM band, Ku-band, K-band, and Ka-band frequency ranges.
• Knowledge of RF transceiver architectures, digital communication systems, spread spectrum, single and multi-carrier techniques, and modulation types such as QPSK, APSK, and QAM.
• Familiarity with RF-related test equipment such as spectrum analyzers, vector signal analyzers, vector signal generators, network analyzers, and hands-on experience in a lab with equipment for RF testing and measurement.
