Conventional Pin Diode Limiters

Cobham Signal & Control Solutions - Conventional Pin Diode Limiters

PIN diode limiters are built to protect sensitive circuit elements such as receiver front ends or detectors. They reduce high power inputs to a low level that can be tolerated by the next component.

Limiters may be categorized as conventional or feedback types.

Our family of conventional limiters typically exhibits leakage levels up to +20dBm with recovery times less than 40nsec. These models handle up to 100W peak power levels and cover the frequency range form 100MHz to 40GHz.

Custom models with higher power handling available.

Features:
  • Low Insertion Loss
  • Low Leakage Power Circuit Protection
  • High CW Power Handling
  • Hermetically Sealed Modules
  • Assorted Package Styles
  • Custom Designs Available

Notes:


1) Typically CW leakage is measured at mid-band with 1W input.
2) Higher power handling available. Contact the factory to discuss specific requirements.
3) Power handling is linearly derated from full power at +25°C to zero power at +150°C.
