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). RF path requires a 10 nF dc blocking capacitor.

Exposed Paddle

GND. Solder this paddle to a low impedance ground plane.
