• Low Loss, 0.3 dB Typical @ 900 MHz
• 2.5 to 5.0 Volt Operation
• SOT-25 Plastic Package
• Tape and Reel Packaging Available
Description
M/A-COM’s AT-267 is a 1-bit, 15-dB step GaAs
MMIC digital attenuator in a low cost SOT-25, 5 lead
surface mount plastic package.
ideally suited for use where high accuracy, very low
power
products are required.
Typical applications include wireless handsets, base
stations, wireless LAN equipment, GPS receivers
and any RF applications with automatic gain/level
control circuits.
The AT-267 is fabricated as a monolithic GaAs
integrated circuit using a mature PHEMT process.
The process features full chip passivation for
performance and reliability.
