The M/A-COM MAATSS0002 is a 1 dB step GaAs MMIC
digital attenuator with 31.0 dB dynamic range in a low cost
QSOP-16 (SSOP-16) package. It requires external DC
blocking capacitors on the RF ports, positive supply voltage
and five individual bit control voltages. It 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 MAATSS0002 is fabricated using M/A-COM’s GaAs
1.0 micron process. The process features full chip
passivation for increased performance and reliability.
