RF Detectors

JFW RF Detector Output VoltageJFW’s online RF detector models are listed in the table below.  Our RF detectors use a circuit with a zero-biased Schottky detector diode to convert the RF input signal into a DC output signal.  As the amount of RF input power varies so does the DC output signal level.

RF detectors are typically used for RF detection on a RF path.  Insert a directional coupler into the RF path with the RF detector on the coupled port.  The coupled RF signal will be converted to a DC signal by the RF detector.  The DC signal can then be used by a microprocessor to determine whether RF is present on the RF path based on the amplitude of the DC signal level.

  • RF Detectors available with positive or negative DC outputs
  • 50 Ohm and 75 Ohm impedance models available
  • Various connector combinations available (i.e. N/SMA, SMA/BNC)

For your specific application, please contact JFW for assistance or use our Inquiry Form.
