C-MEMS Research – Reliability control of RF-MEMS switches

RF-MEMS for Wireless Applications

  • Mobiles, satellite comms, automotive electronics, etc
  • Reduced weight, volume and power consumption, higher data rates and increased functionality

MEMS Switch Characteristics

  • Superb RF performance (high isolation, low insertion loss, high linearity), near-zero power consumption, low-cost
  • Poor dynamic performance: low speeds, weekly damped oscillatory modes, pull-in effect (stable -> unstable dynamics), bouncing phenomenon

Our Work

  • Dynamic performance modeling – nonlinear system identification
  • Study failure modes and mechanisms – Finite element modeling
  • Optimal drive voltage waveform design (soft landing)
