Description
The ATN3580 series of attenuator chips incorporates thin-film
resistors on high-resistivity silicon to achieve precision attenua-
tion, tight flatness and excellent return loss to 40 GHz. The
design uses a balanced TEE resistive structure to assure broad
bandwidth performance. The thin-film technology offers improved
power-handling capability in comparison to the traditional thick-
film printed attenuator. All ATN3580 attenuator chips are
specified for their attenuation at DC. A wafer probe sample test
is performed to 40 GHz to assure the flatness specification.
Characteristic Value
Incident power @ 25 °C 1 W
Operating temperature -55 °C to +150 °C
Storage temperature -65 °C to +150 °C
Absolute Maximum Ratings
Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum Ratings. Exceeding
any of the absolute maximum/minimum specifications may result in permanent damage to the
device and will void the warranty.
CAUTION: Although these devices are designed to be robust, ESD
(Electrostatic Discharge) can cause permanent damage.
Static charges may easily produce potentials of several
kilovolts on the human body or equipment, which can
discharge without detection. Industry-standard ESD
precautions must be employed at all times.
Skyworks Green™ products are RoHS (Restriction
of Hazardous Substances)-compliant, conform to
the EIA/EICTA/JEITA Joint Industry Guide (JIG)
Level A guidelines, are halogen free according to
IEC-61249-2-21, and contain <1,000 ppm antimony
trioxide in polymeric materials.
