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 (V_S) 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.

DC blocking capacitors (C_BL) and biasing resistor must be supplied externally for positive
voltage operation.
C_BL = 47 pF for operation >500 MHz.
