Description

The M/A-COM MAATSS0019 is a 4 Bit, 1 dB step

GaAs MMIC digital attenuator in a lead-free TSSOP-

16

surface

mount

plastic

package.

The

MAATSS0019 is ideally suited for use where high

accuracy, very low power consumption and low

intermodulation products are required.

Typical

applications include radio, cellular, wireless LANs,

GPS equipment and other gain / level control

circuits.

The MAATSS0019 is fabricated using a mature 1

micron GaAs MESFET process.

The process
