Description

M/A-COM’s MAATSS0022 is a 0.5 dB step GaAs

MMIC digital attenuator with 15.5 dB attenuation

range in a lead-free MSOP-10 package. It requires

external DC blocking capacitors on the RF ports,

positive supply voltage and five individual bit control

voltages.

The MAATSS0022 is particularly suited where high

attenuation accuracy, low insertion loss and low

intermodulation products are required.

Typical

applications include base stations, wireless data,

and wireless local loop gain level control circuits.

The MAATSS0022 is fabricated using M/A-COM’s

GaAs 1.0 micron process. The process features full

chip passivation for increased performance and

reliability.
