See table on previous page for CBP value. See application notes APN2013 and APN2014 for 6 bit attenuator requirements. 3 4 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 particularly 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. NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of Hazardous Substances)-compliant packaging.

Recommended Solder Reflow Profiles Refer to the “Recommended Solder Reflow Profile” Application Note. 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 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.
