Functional Schematic
Description
M/A-COM's MAAD-009171-000100 is a GaAs FET
2-bit digital attenuator with two 16 dB steps and 32
dB total attenuation with integral TTL driver. This
design has been optimized to minimize phase
variation over the full attenuation range. This
attenuator is in an RoHS compliant PQFN plastic
surface mount package. MAAD-009171-000100 is
ideally suited for use where accuracy, fast switching,
very low power consumption and low
intermodulation products are required. Typical
applications include dynamic range setting in
precision receiver circuits and other gain/leveling
control circuits.
