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.
