Description
M/A-COM’s 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.
