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.

4. Exposed pad must be connected to RF ground to obtain specified attenuation.
5.Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.
1. All measurements made in a 50 Ω system, unless otherwise specified.
2. Insertion loss changes by 0.003 dB/°C.
3. Attenuation value referenced above insertion loss.
