RF-MEMS

MEMS RF switches are miniaturized mechanical devices for switching high frequency electromagnetic signals.

The advantages of MEMS RF switches compared to PIN diodes and field-effect transitors (FETs) are minimum insertion loss, maximum isolation, a superior signal linearity, and a very low power consumption.

Protron Mikrotechnik develops electrostatic RF switches which are suitable for an application in

• mobile communication systems
• RF test equipment
  
• radar systems
  
• satellites

Protron's RF switches are actuated by electrostatic silicon comb drives with a high actuation force which results in a good reliability. The switch concept can be adapted to frequencies from DC to about 12GHz in series or shunt implementation. A hermetic zero-level packaging avoids contamination of the contact area. The switch is designed as a discrete chip suitable for flip-chip or wire bonding.
