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

1. All measurements made in a 50 Ω system, unless otherwise specified.

2. Operates to DC when controlled with negative voltage, C

3. Attenuation value set by C

4. Attenuation referenced to insertion loss.

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.
