Description
The AA106-86 is a 5 bit, single positive control GaAs IC
FET digital attenuator in a low cost MSOP-10 package.This
attenuator has an LSB of 0.5 dB and a total attenuation of
15.5 dB. The attenuator requires external DC blocking
capacitors, positive supply voltage (V_S) and five individual
bit control voltages (V₁–V₅). The AA106-86 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.
