Description The AA264-87 is a 4 bit, single positive control GaAs IC FET digital attenuator in a low cost TSSOP-16 package.
The attenuator requires external DC blocking capacitors, positive supply voltage (VS) and four individual positive control voltages (V1–V4).
The AA264-87 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 control circuits.
