Digital Attenuator, 1 Bit, 10 dB Step
DC - 2.0 GHz
Features
• Single 10 dB Step
• Low Loss: 0.3 dB @ 900 MHz
• Low Cost SOT-25 Package
Description
M/A-COM’s AT-266 is a 1 bit, 10 dB step GaAs
MMIC digital attenuator in a low cost SOT-25
surface mount plastic package.
ideally suited for use where high accuracy, very low
power
products are required. Typical applications include
radio, wireless LANs, GPS equipment and other
gain/level control circuits.
The AT-266 is fabricated using a mature GaAs
MMIC process featuring full chip passivation for
increased performance and reliability.
