Description
The AA105-86 is a 4-bit, single positive control GaAs IC FET
digital attenuator. It requires DC blocking capacitors, positive
supply voltage (V_S) and four individual positive bit control volt-
ages (V₁–V₄). The AA105-86 is particularly suited where high
attenuation accuracy, low insertion loss and low intermodulation
products are required. Typical applications include cellular radio,
wireless data, and wireless local loop gain level control circuits.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
