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.
