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 intermodulation 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.

Application Information
The on chip charge pump oscillates at approximately 600 KHz, which may create noise in the user's circuit. When the input level to the attenuator is low, < -10 dBm, the signal to noise ratio starts to degrade. For many applications, input power levels are typically in the -20 dBm to -30 dBm range. At these input levels there is insufficient signal to noise. Skyworks has developed a solution to this problem. Part number AA117-85 has the same attenuation range as the AA110-85, but the charge pump oscillator has been turned off. The user can still control the part with 0/+V, however a negative VSS voltage is required. See AA117-85 data sheet for further information.
