DD02-92, DD02-92LF: Directional Detector
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 DD02-92 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 A.

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.
