High Sensitivity Zero Bias Schottky Detectors
3 dB More Sensitive than Regular Crystal or Zero Bias Schottky Detectors
100 KHz to 26.5 GHz
FEATURES
  • No bias required
  • Matched input for excellent VSWR
  • 3 dB more sensitive (1.0 mV/micro W) than traditional matched zero bias detectors
  • Very wide dynamic range, 10 microV to 5V (for input power -50 dBm to +20 dBm)
  • Extremely flat frequency response
APPLICATIONS
  • Lab testing
  • Power monitoring
  • Leveling circuit
