per JEDEC J-STD-020
Description
The AA264-87 is a 4-bit, single positive control GaAs IC FET dig-
ital attenuator in a low-cost TSSOP-16 package. The attenuator
requires external DC blocking capacitors, positive supply voltage
(VS) and four individual positive control voltages (V1–V4). The
AA264-87 is particularly suited where high attenuation accuracy,
low insertion loss and low intermodulation products are required.
Typical applications include base station, wireless data and wire-
less local loop gain control circuits.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
