Description

M/A-COM’s MAATSS0020 is a 5-bit, 1-dB step

GaAs MMIC digital attenuator in a lead-free SSOP-

20

surface

mount

plastic

package.

The

MAATSS0020 is ideally suited for use where high

power 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 MAATSS0020 is fabricated with a monolithic

GaAs MMIC using a mature 1-micron process.

The process features full chip passivation for in-

creased performance and reliability.
