Description
The DD02-999 directional detector is designed to operate from
650 MHz to 3 GHz. It contains a high-directivity directional
coupler, the coupled arm of which drives a GaAs Schottky
detector diode. It also contains an identical GaAs Schottky diode
used for temperature compensation. This part is packaged in the
miniature SC-88 package. The DD02-999LF is packaged in the
lead (Pb)-free SC-88 package and is fully compliant with current
RoHS requirements.
The DD02-999 provides detection of the input signal amplitude
only, by virtue of the directivity of the on-chip directional coupler.
The sensitivity of the detector diode is improved through the
application of an external 5 µA (nominal) forward bias current
produced by an external 1 V (nominal) voltage source. This bias
current is also applied to the temperature compensation diode.
Temperature compensation of the detected output voltage can be
accomplished by subtracting the output voltage from the temperature compensation Schottky diode, which is thermally coupled
to the detector Schottky diode via their common substrate, from
the detected output voltage.
This part is rated to operate from -40 °C to 85 °C.
An evaluation board is available upon request.

CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce potentials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
