* The 2.4 pF cap can be placed at the same point as the 1.8 nH inductor
which should be as close as possible to the DC blocking cap (10 pF). The
placement can be modified for the best linear performance. A series
capacitor (10 pF) must be added to provide a DC block after the 2Fo Filter.
**Pin 4 must be left as a no-connect on the PCB.
