Description
The AA101-80 is a 5-bit, single positive control GaAs IC FET
digital attenuator in a low-cost SSOP-16 package. This attenuator
has an LSB of 1 dB and a total attenuation of 31 dB. The
attenuator requires external DC blocking capacitors, positive
supply voltage (V_S) and five individual bit control voltages (V₁–V₅).
The AA101-80 is particularly suited where high attenuation
accuracy, low insertion loss and low intermodulation products
are required. Typical applications include base station, wireless
data, and wireless local loop gain level control circuits.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
