GaAs IC 5 Bit Digital Attenuator
1 dB LSB DC–2 GHz
Features
s Attenuation 1.0 dB Steps to 31 dB
with High Accuracy
s Low DC Power Consumption
s Low Cost SSOP-20 Plastic Package
Description
The AA260-85 is a 5 bit, GaAs IC FET digital attenuator
in a low cost SSOP-20 package. This attenuator has an
LSB of 1 dB and a total attenuation of 31 dB. The
AA260-85 is particularly suited where high attenuation
accuracy, low insertion loss and low intermodulation
products are required. Typical applications include
cellular radio, wireless data, wireless local loop and other
gain level control circuits.

1. All measurements made in a 50 Ω system, unless otherwise specified.
2. DC = 300 kHz.
3. Attenuation referenced to insertion loss.
4. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.
*Due to conflict with another company’s product numbering system, Alpha’s attenuator products starting with the letters “AD” are being changed to “AA”.
