Description
The AA210-25 is an IC FET digital attenuator consisting of four
monolithic attenuators with LSB of 1 dB and a total attenuation
of 15 dB with all attenuators connected. Attenuator bits are
switched with -5 and 0 V. The AA210-25 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.
