Description
M/A-COM'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.
