AAT2075B2 Data Sheet
75Ω Digital Attenuator 2-Bit 15dB DC~2700 MHz
1. Product Overview
1.1 General Description
The AAT2075B2 is a GaAs MMIC two bit positive control digital attenuator. The device operates from DC to
2700 MHz with a control and supply voltage of +3 V or +5 V. The AAT2075B2 has LSB of 5 dB and a total
attenuation of 15dB. The AAT2075B2 is composed of two cascade fixed attenuators. The states of attenuator
are controlled by the logic level voltage. The attenuator bit values are 5 dB (LSB), 10dB for a total attenuation
of 15dB. Attenuation accuracy is ±(0.15 dB + 3 % of attenuation setting) @ DC~1200 MHz.
