Description

M/A-COM’s MAATSS0021 is a 5-bit, 0.5-dB step

GaAs MMIC digital attenuator in a lead-free SOIC-16

surface mount plastic package. The MAATSS0021 is

ideally suited for use where high accuracy, fast

switching, very low power consumption and low

intermodulation products are required at a low cost.

Typical applications include radio and cellular

equipment, wireless LANS, GPS equipment and

other gain/level control circuits.

The MAATSS0021 is fabricated with a monolithic

GaAs MMIC using a mature 1-micron process. The

process features full chip passivation for increased

performance and reliability.
