Description
M/A-COM’s MAATSS0021 is a 5-bit, 0.5-dB step
GaAs MMIC digital attenuator in a lead-free SOIC-16
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.
