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.
