The SL3521 used in this circuit is a successive-detection log amp IC for use in the 100- to 650-MHz range. The IC provides a video output with offset adjust. Figure 2-3B shows the pin connections. Figure 2-3C shows the electrical characteristics. The offset voltage at pin 2 should be in the -0.45- to -0.55-V range, and must not be such as to increase the output offset to more than±0.5 V
