Description
M/A-COM’s AT-264 is a 4-bit, 2-dB step GaAs MMIC
digital attenuator in a low cost TSSOP-16 surface
mount plastic package. The AT-264 is ideally suited for
use where high accuracy, very low power consumption
and low intermodulation products are required. Typical
applications include radio, cellular, wireless LANs, GPS
equipment and other gain/level control circuits.
The AT-264 is fabricated using a mature 1 micron
GaAs MESFET process. The process features full chip
passivation for increased performance and reliability.

2. Blocking caps are required on all RF ports (39 pF used
for data measurements).
3. Vs = +5 ± 0.2 VDC must be applied at RF1 or RF2 using
a 10 Kohm or greater pull-up resistor.
