Description
The AA107-310 is a GaAs FET IC 5-bit digital attenuator with a serial-to-parallel driver packaged in a 32-leadless exposed pad plastic package. It is particularly suited at IF frequencies where high attenuation accuracy, low insertion loss, and low intermodulation products are required. Typical applications include base station, wireless and RF data and wireless local loop gain control circuits.

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.
