Padded Zero Bias Schottky Detector

Cobham Signal & Control Solutions - Padded Zero Bias Schottky Detector

Detectors with internal attenuators are often requested. They are typically used in circuits where an improved RF match is needed or where the power levels applied are higher than is typical for low level detectors. Frequently, they are used in laboratory applications with associated instruments such as broadband power leveling or monitoring. These detectors are all zero bias, making them convenient to use.

  1. Available in both negative and positive polarities, substitute "N" or "P" in part number.
  2. Measured into an open circuit load (>10k ohm).
  3. Video protection is available on most models. This feature helps to prevent damage to the detector diode from incidents occurring at the video port. Transient electromagnetic spikes, static contact, or voltage surges can easily damage a detector diode. A video protection diode will clamp the voltage at a value less than the detector breakdown voltage. NOTE: Inclusion of this protection will cause the output voltage to compress and clamp. This occurs at about +10dBm input to the detector. If operation above +10dBm is required then the output protection should be modified or excluded. Adding a suffix "X" at the end of the model number will exclude the video protection feature. Contact the factory for assistance.
