First Section (LNA)
The LNA section may be left unused. Power
is not connected to pin 1. The performance
is then as specified for the Second Section
(Mixer).

Input IP3
+4
dBm
IP3 may be increased 10dB by connecting
pin 22toVCC through the matching inductor.
The LNA’s current then increases by 10mA.
Other in-between IP3 versus ICC trade-offs
may be made. See pin description for pin 20.
