The DD02-92 directional detector is an alternative to the DD01-92
with improved insertion loss and directivity with slightly lower
sensitivity. It is designed for handset power monitor applications
from 800 MHz to 3 GHz. It is packaged in the small footprint,
SC-88 (6 lead SC-70) package. The DD02-92 incorporates a
directional coupler and two GaAs Schottky diodes on a monolithic
GaAs chip. By applying forward DC bias to both Schottky diodes,
the DD02-92 may be conveniently temperature compensated. The
DD02-92 is characterized from 500 MHz to 3 GHz and generates
a detected signal at 1.8 GHz of approximately 190 mV at 10 mW
input power. Each Schottky diode is forward biased to approximately 5 µA.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, Electrostatic Discharge (ESD) 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.
