Note:
*If DC Voltage is at Pin 5 from the
device after the LNA, then an external
DC-blocking capacitor is needed due
to the internal shunt inductor on Pin 5
as shown in the schematic above.
** On the evaluation board adding
C1, which is 1 uF, did not make any
difference but could be needed
depending on the layout and the
nature of the supply voltage used in
the system.
