80 mm) 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 (VS) and five individual bit control voltages (V1–V5).
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.
