Description
M/A-COM’s MAATSS0021 is a 5-bit, 0.5-dB step
GaAs MMIC digital attenuator in a lead-free SOIC16
surface mount plastic package. The
MAATSS0021 is ideally suited for use where high
accuracy, fast switching, very low power
consumption and low intermodulation products are
required at a low cost.
