Fig 3. Application diagram
001aao044
Figure 3 shows a typical application circuit. Both RF and RF reference pins need to be AC
coupled. The inputs are internally DC biased in order to provide good ESD protection, and
to support large input signals without clamping. The output matching requires a
transformer to cope with the DC at the output.
