DATA SHEET
AA226-87, AA226-87LF: GaAs IC 4-Bit Digital Attenuator,
1 dB LSB LF–2.5 GHz
Features
Attenuation 1 dB steps to 15 dB with high accuracy
Single positive control (3 to 5 V) for each bit
Low DC power consumption
Small low-cost TSSOP-16 plastic package
Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C
per JEDEC J-STD-020
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.
