Description

The AA280-25 is a 5-bit, GaAs IC FET digital attenuator in a low- cost SOIC-16 package. This attenuator has an LSB of 0.5 dB and a total attenuation of 15.5 dB. The AA280-25 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include cellular radio, wireless data, wireless local loop and other gain level control circuits. Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

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 specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce poten- tials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times. Recommended Solder Reflow Profiles Refer to the “Recommended Solder Reflow Profile” Application Note. Tape and Reel Information Refer to the “Discrete Devices and IC Switch/Attenuators Tape and Reel Package Orientation” Application Note.
