Description
The AD230-24 is an IC FET Digital Attenuator consisting
of three monolithic attenuators with LSB of 4 dB and a total
attenuation of 28 dB with all attenuators connected.
Attenuators are switched with -5 and 0 V.
The AD230-24 is particularly suited where high
attenuation accuracy, low insertion loss and low
intermodulation products are required.Typical applications
include cellular radio, wireless data, wireless local loop and
other gain level control circuits.
