Description
The DC08-73 is a monolithic directional coupler optimized for the
0.81–0.96 GHz band. It offers low loss, good isolation, good
input/output matching and exceptional coupling repeatability. It
may be used at higher frequencies when stronger coupling is
required. It is available in the SOT-6 surface mount package.
NEW
Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
