Description
The AA101-80 is a 5 bit, single positive control GaAs IC
FET digital attenuator in a low cost SSOP-16 package.
This attenuator has an LSB of 1 dB and a total attenuation
of 31 dB. The attenuator requires external DC blocking
capacitors, positive supply voltage (V
S
) and five individual
bit control voltages (V
1
–V
5
).The AA101-80 is particularly
suited where high attenuation accuracy, low insertion loss
and low intermodulation products are required. Typical
applications include base station, wireless data, and
wireless local loop gain level control circuits.
