The ATN3584 series of ceramic packaged fixed attenuators
are specified from DC–7 GHz in micro-X outline surface
mount packages. They are constructed using thin film
resistors in a balanced TEE configuration on silicon
substrates, resulting in precise devices with narrow
tolerance, good flatness and low SWR.
