Attenuation 1 dB Steps 31 dB with High Accuracy Single Positive Control +5 V) for Each Bit Low DC Power Consumption Small Low Cost SSOP-16 Plastic Package
Description
The a 5 bit, single positive control GaAs IC FET digital attenuator in a low cost SSOP-16 package. This attenuator has an LSB 1 dB and a total attenuation of 31 dB. The attenuator requires external DC blocking capacitors, positive supply voltage (VS) and five individual bit control voltages (V1V5). The AA101-80 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data, and wireless local loop gain level control circuits.
