Qorvo US, Inc. Senior Microwave SSPA Design Engineer in Chelmsford, Massachusetts
The successful candidate will design and develop high-power RF amplifier circuits and modules using MMICs of various types of advanced state-of-the-art compound semiconductor technologies. You will be a key member of an integrated product development team that includes marketing, program management, mechanical engineering, product engineering, package engineering, test engineering, applications engineering, manufacturing, operations, quality and reliability, and senior management. RESPONSIBILITIES Technical lead role designing high power SSPAs ranging in frequency from 2-100 GHz. The candidate will be responsible for all aspects of the SSPA electrical design. Primary design-facing tasks include (but are not limited to): Schematic capture and circuit layout using various substrate technologies RF circuit analysis using 2.5D (ADS or MWO) and 3D (HFSS) simulators. Generate then present design review documentation in a group forum of peers and internal and/or external customers. Execute and/or supervise product level checkout, debug, optimization, and design verification testing (DVT) in the engineering lab. Test Plan Definition Component selection, characterization, and BOM management Collaborate closely with the assigned Mechanical Design Engineer to ensure the design is viable from a thermal and mechanical perspective. The candidate will communicate and collaborate with members of a cross-functional new product development (NPD) team. This includes peers in Design, Assembly, Test, Program Management, Quality, and CAD. Support all stages of the product lifecycle including design, assembly, test, qualification, production support, and customer support. REQUIRED QUALIFICATIONS & EXPERIENCE: BS degree in Electrical Engineering, Engineering Physics, or equivalent with a minimum of 8 years of industry experience. Alternatively, a combination of three years of industry experience plus relevant RF/Microwave focused post-doctoral experience is acceptable. Practical experience designing and releasing high power RF amplifiers to the commercial or aerospace and defense market is required. This includes knowledge of: Transmission line structures (microstrip, waveguide, coaxial) Power combining techniques (planar, spatial, waveguide) Impedance matching techniques RF PA biasing modes Electrothermal behavior of compound semiconductor devices Analog bias control circuits Multi-layer RF PCB design MIL-SPEC Design / Test Requirements Expert user of EDA tools for linear, nonlinear, and electromagnetic (EM) simulations: Linear and non-linear analysis using MWO (Cadence) and/or ADS (Keysight) 2.5D EM simulation (Axiem or Momentum) 3D EM simulation (HFSS) SPICE simulation. Relevant experience designing RF power amplifier modules with GaN and/or GaAs technologies. Extensive experience designing passive microwave components including power dividers and combiners, transmission lines, couplers, impedance matching networks, antennas. A broad working knowledge of RF semiconductor packaging and assembly processes is strongly preferred. Hands-on lab experience using RF test equipment (network and spectrum analyzers, signal generators, power meters, oscilloscopes, etc.) Must be a good team player with a positive attitude and a desire to learn and grow intellectually as technology and tools evolve. Good communication, organization, and documentation skills. Self-motivated with strong problem solving and critical thinking skills.
