Description
The AA106-86 is a 5-bit, single positive control GaAs IC FET dig-
ital attenuator in a low-cost MSOP-10 package. This attenuator
has an LSB of 0.5 dB and a total attenuation of 15.5 dB. The
attenuator requires external DC blocking capacitors, positive
supply voltage (VS) and five individual bit control voltages (V1–V5).
The AA106-86 is particularly suited where high attenuation accu-
racy, 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.
