AT-264
Digital Attenuator, 4-Bit, Single Control
30 dB, 0.5 - 2.0 GHz
Features
• Positive Single Control
• 2-dB Attenuation Steps to 30 dB
• Low DC Power Consumption
• TSSOP-16 Plastic Package
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.
