Description
MACOM's MAAD-009170-000100 is a GaAs pHEMT
5-bit digital attenuator with integral TTL driver in an
PQFN plastic surface mount package. Step size is
0.5 dB providing a 15.5 dB total attenuation range.
This design has been optimized to minimize phase
variation over the attenuation range. MAAD-009170-
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.
