PA Designer

Skyworks Woburn design center is seeking a design engineer responsible for the development of RF high power amplifiers modules for the wireless infrastructure market, including Class A/B, Doherty, and other high efficiency advanced topologies. Average output power levels range from 1 to 20W. Designs will be Multi-Chip Modules, implemented in GaAs (HBT/pHEMT), GaN, as well as various IPD processes. Individual should have experience in RF & 3D EM modeling and simulation of complete module, tuning and bench evaluation of PA parameters such as gain, linearity, PAE, P3dB, VBW, input/output matching and stability. Familiarity with high power RFIC design, thermally enhanced packaging techniques and substrate technologies is required. Candidate should have experience with complete cycle of development for high-performance, high-volume semiconductor products.

Ideal candidate must be able to work efficiently in the fast paced wireless infrastructure market, understand the importance of time to market, and be able to face challenging tasks to meet critical performance parameters.

Job Responsibilities:

  • Familiar with die level thermal simulation requirements, and with thermally enhanced packaging techniques.

  • Responsible for translating system level specs into circuit block level performance specs, circuit architecture, design and development to meet the system level specs.

  • Good knowledge and understanding of laminate, wire bonding, WLCSP techniques, SMT components. Expertise in on-die and in-module RF coupling mechanisms, isolation techniques and shielding methods is required.

  • Responsible for managing design tradeoffs on performance, risk, yield, testability and cost.

  • Layout floorplan to optimize performance, layout supervision, post layout simulations.

  • Ability to manage the assigned project with minimum supervision.

  • Responsible for transistor level RF and analog circuit design based on system requirements

  • IC & MCM layout supervision

  • IC / MCM lab test and debug


  • BS Degree and 12 years’ experience required, MSEE or Ph.D. preferred.

  • Familiar with amplifier modes of operation: Class A, AB, C, F, F-1, E and load modulation techniques such as Doherty PA design and Outphasing.
