Description
The AA105-86 is a 4-bit, single positive control GaAs IC FET
digital attenuator. It requires DC blocking capacitors, positive
supply voltage (V
S
) and four individual positive bit control volt-
ages (V
1
–V
4
). The AA105-86 is particularly suited where high
attenuation accuracy, low insertion loss and low intermodulation
products are required. Typical applications include cellular radio,
wireless data, and wireless local loop gain level control circuits.
