DATA SHEET 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 Pin Out 6 RF In 5 DC Bias/AC GND 4 3 Temp Comp Out DD2 DC Bias/AC GND 2 NEW RF Out 1 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. Detected Out Skyworks offers lead (Pb)-free “environmentally friendly” packaging that is RoHS compliant (European Parliament for the Restriction of Hazardous Substances).
