Description
The AA110-85 is a 5-bit, single positive control GaAs IC FET digital
attenuator with driver. It is particularly suited at IF frequencies
where high attenuation accuracy, low insertion loss and low inter-
modulation products are required. Typical applications include base
station, wireless data, broadband and wireless local loop gain
control circuits. For low-power applications (< -10 dBm) see part
number AA117-85.
