DD02-999, DD02-999LF: Directional Detector
DATA SHEET
Features
Frequency coverage: 650 MHz to 3.0 GHz
Typical insertion loss < 0.2 dB to 2.3 GHz
Typical directivity > 23 dB
Small outline SC-88 (6 Lead SC-70)
Built-in temperature compensating diode
Low cost for high-volume handset applications
Available lead (Pb)-free MSL-2 @ 250 C per JEDEC J-STD-020
Description
The DD02-999 directional detector is an alternative to the
DD01-999 with improved insertion loss and directivity with slightly
lower sensitivity. It is designed for handset power monitor applica-
tions from 800 MHz to 3 GHz. It is packaged in the small footprint,
SC-88 (6 lead SC-70) package. The DD02-999 incorporates a
directional coupler and two GaAs Schottky diodes on a monolithic
GaAs chip. By applying forward DC bias to both Schottky diodes,
the DD02-999 may be conveniently temperature compensated.
The DD02-999 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 A.

Absolute Maximum Ratings
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 poten-
tials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
