3.1 Schematics

TRF1108-DAC39RFEVM Analog Output Path SchematicFigure 3-1 Analog Output Path Schematic

An attenuation pad approximately equation to 8dB is added between the TRF1108 inputs and the DAC. The 8dB pad helps with the flatness of the frequency response along with preventing saturation of the amplifiers.
