• Develop RF and microwave circuits from DC to 100GHz and beyond.
• Design low‑noise signal conditioning, amplification, control, and power management circuits.
• Perform signal integrity, power integrity, and electromagnetic compatibility analyses.
• Design and characterize photodiode‑based receiver chains, including:
  • Focusing optics
  • Photodiodes
  • Transimpedance amplifiers (TIAs)
  • Distributed amplifiers
  • Receiver front‑end electronics
  • Optical detection and acquisition systems
• Perform HFSS‑based analog simulations and high‑speed signal‑path analysis.

Travel Requirements:
