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. The AT-267 is

ideally suited for use where high accuracy, very low

power consumption and low intermodulation

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.
