Description

The MAATSS0018 is a 1 bit, 10 dB step GaAs

MMIC digital attenuator in a lead-free SOT-25

surface mount plastic package.

The MAATSS0018 is ideally suited for use where

high accuracy, very low power consumption and low

intermodulation products are required. Typical

applications include radio, wireless LANs, GPS

equipment and other gain / level control circuits.

The MAATSS0018 is a GaAs MMIC using a mature

1-micron process. The process features full chip

passivation for increased performance and reliability.
