Description
M/A-COM’s AT90-0233 is a GaAs FET 4-Bit digital
attenuator with integral driver. Step size is 2 dB providing a 30 dB attenuation range. This device is in
an PQFN plastic surface mount package. The
AT90-0233 is suited for use where accuracy, fast
speed, very low power consumption and low costs
are required.
