DC level. At higher input frequencies a transmission line
balun transformer (Figures 4 to 6) has better balance,
resulting in lower A/D distortion.
Amplifier Circuits
Figure 7 shows the analog input being driven by a high
speed differential amplifier. The output of the amplifier is
AC-coupled to the A/D so the amplifier’s output common
mode voltage can be optimally set to minimize distortion.
Figure 4. Recommended Front-End Circuit for
Input Frequencies from 70MHz to 170MHz
At very high frequencies an RF gain block will often have
lower distortion than a differential amplifier. If the gain
blockissingle-ended,thenatransformercircuit(Figures 4
to 6) should convert the signal to differential before driv-
ing the A/D.
