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 partic-

ularly 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.

Electrical Specifications at -40 °C to +85 °C (0, 3 V), (0, 5 V)

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

2. Operates to 300 kHz when controlled with negative voltage, C

3. Attenuation value set by C
