High Frequency Tunnel Detectors

Cobham Signal & Control Solutions - High Frequency Tunnel Detectors

Exceptional thermal stability and flatness vs. frequency characterize these tunnel detectors from Cobham Signal & Control Solutions, Inc. Several models are available which operate over all or a portion of the frequency range of 18 to 40 GHz. The temperature stability is +/- 0.3dB over the range of -65°C to +100°C. The typical output impedance is 115. This allows for extremely fast video response when operating in the square law range, typically -20dBm or lower. The input power rating is +14dBm maximum.

Each detector model contains:
  • DC Return
  • RF Bypass Capacitor
  • Detector Diode
  • Exceptional Temperature Stability
  • Low Video Resistance (115 typical)
  • Broadband Performance
  • No Bias Required
  • Transmitter Monitoring
  • 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
