Description
The DC08-73 is a monolithic directional coupler tailored to 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 leaded surface mount package.
