Zero Bias Detectors

Zero Bias Detector 325 GHz Zero Bias Detector 900 GHz
RPG offers a new series of zero bias waveguide detectors covering the frequency range 50 to 900 GHz. The combination with an associated signalamplifier eliminates the need for external bias supplies and guarantees high tangential sensitivities together with fast response times.

WDT detectors are equipped with UG-387 waveguide flange and additional feed horn antennas if required. A video amplifier power supply is available. If the devices listed here do not match your needs, please feel free to contact us and ask for a custom-designed quotation!

Features

  • RF input bandwidth 10% typical
  • Video bandwidth up to 250 kHz
  • Low noise 5mV @ n=500 video gain
  • Rail to rail signal output
  • No mechanical tuners
