AA264-87, AA264-87LF: GaAs IC 4-Bit Digital Attenuator
2 dB LSB Positive Control 0.5–2 GHz
DATA SHEET
Features
Attenuation 2 dB steps to 30 dB with high accuracy
Single positive control 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 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
(V
S
) and four individual positive control voltages (V
1
–V
4
). 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.
