Description
M/A-COM’s MAATSS0002 is a 1 dB step GaAs
MMIC digital attenuator with 31 dB attenuation
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.
The MAATSS0002 is particularly suited where high
attenuation accuracy, low insertion loss and low
