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
(V

). 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.
