Design and Simulation of a Compact 6–18 GHz Wilkinson Power Divider

Project Description

We are looking for a highly skilled RF engineer to remotely design and simulate a broadband Wilkinson power divider covering the 6 to 18 GHz frequency range. This component will be used in a wideband receiver front-end for radar and test equipment.

The project is focused entirely on simulation and design — no physical prototyping is required.

Objectives:

• Design a Wilkinson power divider using microstrip or stripline technology
• Frequency range: 6 GHz to 18 GHz
• Performance targets:
  • Return loss (S11): < –15 dB over the band
  • Insertion loss: < 1.2 dB
  • Isolation (S23): > 20 dB
  • Phase and amplitude balance: tight control ±0.5 dB / ±5°
• Use a practical substrate (Rogers, Taconic, or equivalent) with manufacturable dimensions
• Ensure the design is suitable for PCB fabrication
• Optimize layout for minimal size and maximum performance

Deliverables:

• Full simulation model (CST, HFSS, ADS, or equivalent)
• Exported S-parameter files (.s2p)
• S11, S21, S31, and S23 plots across the 6–18 GHz range
• 3D layout screenshots and geometry annotations
• Compact PCB layout in DXF or Gerber format
• Short documentation (2–3 pages) covering:
  • Substrate details
  • Key design choices
  • Matching and tuning considerations

Suggested Tools:

• CST Microwave Studio
• Keysight ADS
• HFSS or FEKO

Ideal Freelancer:

• Strong experience with passive RF components
• Prior projects in high-frequency microwave design (10 GHz+)
• Familiarity with broadband Wilkinson or Gysel power dividers
• Ability to deliver manufacturable, simulation-validated results
• Good documentation and communication habits

Timeline: Duration: 2–3 weeks
