Description

M/A-COM’s MAADSS0009 is a 4-bit, 2-dB step

GaAs MMIC digital attenuator in a lead-free SOIC

16-lead surface mount plastic package. The

MAADSS0009 is ideally suited for use where high

accuracy,

fast

switching,

very

low

power

consumption and low intermodulation products are

required. Typical applications include radio and

cellular equipment, wireless LANs, GPS equipment

and other Gain/Level Control circuits.

The MAADSS0009 is fabricated with a monolithic

GaAs MMIC using a mature 1-micron process. The

process features full chip passivation for increased

performance and reliability.
