Description
M/A-COM’s AT90-0413 is a GaAs FET 4-Bit digital
attenuator with integral driver. Step size is 1 dB providing
a 15 dB attenuation range. This device is in an FQFP-N
plastic surface mount package. The AT90-0413 is suited
for applications where accuracy, fast speed, low power
consumption and low costs are required.
