Description
The AA109-310 is a GaAs FET IC 5-bit digital attenuator with a
serial-to-parallel driver packaged in a 32-leadless exposed pad
plastic package. It is particularly suited where high attenuation
accuracy, low insertion loss, and low intermodulation products
are required. Typical applications include base station, wireless
and wireless local loop gain control circuits.
