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.
