Biased Coaxial Schottky Detectors with Internal RF Matching

Cobham Signal & Control Solutions - Biased Coaxial Schottky Detectors with Internal RF Matching

This family of padded input detectors allows for higher input power read and better VSWR than pure biased schottky units. They come in a variety of package styles. Module versions for microstrip or stripline applications are also available.

Each detector model contains:

  • Input Impedance Matching
  • DC return
  • RF bypass capacitor
  • Detector diode
Applications:
  • Transmitter Monitoring
  • Radar Equipment
  • Missile Guidance Systems
  • Input to Low-Noise Amplifiers
  • Broadband Or Narrowband ECM Receivers
  • Power and Signal Monitors
  • Doppler Radar and Beacon Receivers
  • Matched units available for Multi-channel Receivers, Amplitude Comparator Systems and Discriminators

Notes:

  1. Standard output polarity is negative. If positive output is required, substitute “P” for “N” in part number.
  2. Measured into an open circuit load (>10k ohm).
  3. VSWR measured at or below -20dBm input power level.
  4. 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 values other than those shown are needed.
  5. Standard bias is 100 microamps.
  6. Zero bias schottky versions are available for most of listed biased schottky models with only minor differences in specifications.
      a: The zero bias schottky has an impedance of several thousand ohms.
      b: Zero bias schottky detectors exhibit less sensitive TSS due to the high diode impedance (typically a 3dB reduction).
      c: The temperature performance of the zero bias schottky is poor when operating at low input power levels. This difference becomes small at high levels (above 0dBm input power). The part number of zero bias versions includes a "Z" following the polarity indicator.
