Tunnel Diode Detector Modules

Cobham Signal & Control Solutions - Tunnel Diode Detector Modules

The detectors listed are standard products. There are many possible variations, which can be selected as options. Package configurations can be changed if desired. Performance characteristics may be modified to meet special requirements (e.g. the sensitivity might be moved higher or lower with a corresponding effect on VSWR). RF bypass capacitance values can be selected on some models. Contact the factory for special needs.

Notes:

  1. Available in both negative and positive polarities, substitute "N" or "P" in part number.
  2. Diode values can be changed to alter the level of sensitivity. As sensitivity is increased, VSWR will degrade. VSWR will improve as sensitivity is lowered. Flatness and TSS will also be influenced by these changes. If your applications require something special, please contact the factory.
  3. Tangential Signal Sensitivity (TSS) is a measure of low level sensitivity with respect to noise. It is measured using a video amplifier with a 20MHz bandwidth and a 3dB noise figure.
  4. VSWR measured at or below -20dBm input power level.
  5. Video capacitance is used for RF bypass. This value can be changed if required for video response time or other considerations. Contact the factory if value other than those shown are needed.
