Description
The AA117-85 is a 5-bit, single positive control GaAs IC FET dig-
ital attenuator with driver. It is particularly suited at IF frequencies
where high attenuation accuracy, low insertion loss and low
intermodulation products are required. Typical applications
include base station, wireless data, broadband and wireless local
loop gain control circuits. For single supply design and higher
input signal levels, see AA110-85.
