Features, Applications
GaAs IC 5 Bit Digital Attenuator with Driver 1 dB LSB Positive Control DC2 GHz

Attenuation 1 dB Steps 31 dB With High Accuracy Single Positive Control +5 V) for Each Bit Low DC Power Consumption CMOS Integrated Silicon Driver, Positive and Negative Supplies Required Designed for Use at IF Frequencies High Noise Linearity @ PIN < -10 dBm


The a 5 bit, single positive control GaAs IC FET digital attenuator with driver. It is particularly suited at IF frequencies where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data, broadband and wireless local loop gain control circuits. For single supply design and higher input signal levels, see AA110-85.
