Description

The AA104-73 is a 1-bit, GaAs IC FET digital attenuator in a low-cost

SOT-6 package. This attenuator has up to 32 dB total attenuation. The

attenuator requires two lines of voltage control. The AA104-73 is partic-

ularly suited where high attenuation accuracy, low insertion loss, and

low intermodulation products are required. Typical application is as a

sixth bit value for the AA260-85 and AA101-80. A total attenuation of

63 dB in 1 dB steps can be obtained by combining the two attenuators.

Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances)-compliant packaging.

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.
