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. Parameter1 Condition Frequency 2 Min. Typ. Max.

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 ”.
