Description
M/A-COM’s MAADSS0009 is a 4-bit, 2-dB step
GaAs MMIC digital attenuator in a lead-free SOIC
16-lead surface mount plastic package. The
MAADSS0009 is ideally suited for use where high
accuracy, fast switching, very low power
consumption and low intermodulation products are
required. Typical applications include radio and
cellular equipment, wireless LANs, GPS equipment
and other Gain/Level Control circuits.
