Description
The AT001D6-25 is an IC FET digital attenuator consisting
of four monolithic attenuators with LSB of 3 dB and a total
attenuation of 45 dB with all attenuators connected.
The attenuator is packaged in the plastic 16 lead surface
mount package for low cost commercial cellular radio
applications.
