AAT530B6
0.5 ~ 3.0 GHz LSB 0.5 dB, 6 Bit Digital Attenuator
Block Diagram
Overview
The AAT530B6 is a GaAs MMIC binary-weighted six bit positive control digital attenuator. The device operates from 0.5 to 3.0 GHz
with a control and supply voltage +3 V. The AAT530B6 has and LSB of 0.5 dB and total attenuation of 31.5 dB. An external supply
voltage of 3 V is required. The AAT530B6 is composed of six cascaded fixed attenuators. The state of attenuators is controlled by the
logic level voltage. The attenuator bit values are 0.5 (LSB), 1, 2, 4, 8, 16 dB for a total attenuation of 31.5 dB. Attenuation accuracy is
excellent at ±0.3 dB typical step error with an IIP3 of +42 dBm.
