 Skyworks Irvine design center is seeking a skilled 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 0.5W to 20W.  Designs will be RFICs and IPDs in a variety of technologies including GaAs HBT/PHEMT, GaN on SI/SiC and multi-chip modules. 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 development cycle from design to production release 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.



  • 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, debug, and optimization
  • Support customer related issues and responses.



  • 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.
  • Excellent Oral and written communication skills.
  • Familiar with implementation of on chip ESD protection strategies for HBM, and CDM.
  • Strong Lab experience to perform IC / MCM characterization and debugging.
  • Strong hands on experience of Lab equipment including RF signal generators, spectrum analyzer, VNA, power sensor, oscilloscope, and loadpull system.
  • Familiar with wide instantaneous bandwidth LTE waveforms.
  • Familiar with DPD, and memory effects, and how those impact PA design.
  • RFIC design experience using GaAs HBT and or pHEMT of PAs and bias networks, passive components including couplers and matching networks is a must.  Experience with silicon IPD, GaN, or LDMOS is a plus.
  • Proficient with Electromagnetic simulation tools such as HFSS, Momentum/FEM, EMX and with design simulation tools such as Keysight ADS, Cadence, etc.
  • Team player with a strong sense of urgency to meet product requirements schedule.

Desired Skills


  • Experience designing RF power amplifiers.
  • Experience in designing filters, couplers, and other passives in IPD process.
  • Understanding of wafer fabrication process and its effect on circuit performance and yields.
  • Proficient with RF circuit measurements and evaluation
