500 mm) BSC Description The AA105-86 is a 4 bit, single positive control GaAs IC FET digital attenuator.
It requires DC blocking capacitors, positive supply voltage (VS) and four individual positive bit control voltages (V1–V4).
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.
