Description
M/A-COM’s MAADSS0018 is a 5-bit, 0.5-dB step
GaAs MMIC digital attenuator in a lead-free 3mm 16
lead PQFN surface mount plastic package. The
MAADSS0018 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 MAADSS0018 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.
3. Blocking capacitors are required on all RF ports
