Description
The AA100-59LF is a 3 bit, single positive control, 4 dB step GaAs
IC FET digital attenuator in a low cost MSOP-8 plastic package.
For positive operation external DC blocking capacitors are
required on all RF ports. The AA100-59LF is particularly suited
where high attenuation accuracy, low insertion loss and low
intermodulation products are required.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
