Description
M/A-COM’s MAADSS0013 is a 4-bit, 1-dB step
GaAs MMIC digital attenuator in a lead-free 3mm
PQFN-16LD surface mount plastic package. The
MAADSS0013 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 MAADSS0013 is part of a digital attenuator
family. This family includes 4, 5, and 6 bit
attenuators with 0.5, 1, or 2 dB steps and up to 31.5
range.
