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 DD02-999LF provides detection of the input signal amplitude only, by virtue of the directivity of the on-chip directional cou- pler. The sensitivity of the detector diode is improved through the application of an external 5 A (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 temper- ature 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. NeW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.
