AA104-73
Description
The AA104-73 is a 1 bit, GaAs IC FET digital attenuator in
a low cost SOT-6 package. This attenuator has up to
32 dB total attenuation.The attenuator requires two lines of
voltage control.The AA104-73 is particularly suited where
high attenuation accuracy, low insertion loss and low

intermodulation products are required.Typical application
is as a sixth bit value for the AA260-85 and AA101-80.A total
attenuation of 63 dB in 1 dB steps can be obtained by
combining the two attenuators.
