No Connect.
2
RFIN
RF Input. Requires a 10 nF dc blocking capacitor.
5
CLIN
A 1 nF capacitor connected between Pin 5 and ground provides decoupling for the on-board linearizer.
7
RFOUT
RF Output and Bias. DC bias is provided to this pin through a 470 nH inductor (Coilcraft 1008CS-471XJLC or
equivalent). The RF path requires a 10 nF dc blocking capacitor.
EP
Exposed Pad
GND. Solder this pad to a low impedance ground plane.
