Description

The AA226-87 is a 4-bit, single positive control GaAs IC FET dig-

ital attenuator. It requires DC blocking capacitors, positive supply

voltage (VS) and four individual positive bit control voltages

(V1–V4). The AA226-87 is particularly suited where high attenua-

tion accuracy, low insertion loss and low intermodulation

products are required. Typical applications include base station,

wireless data and wireless local loop gain control circuits.

NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of

Hazardous Substances)-compliant packaging.
