Description

1

RFIN

RF Input. Requires a dc blocking capacitor.

2, 3, 6, 7

GND

Ground. Connect these pins to a low impedance ground plane.

4

CB

Low Frequency Bypass. A 1 μF capacitor should be connected between this pin and ground.

5

VPOS

Power Supply for Bias Controller. Connect directly to external power supply.

8

RFOUT

RF Output and Supply Voltage. DC bias is provided to this pin through an inductor that is tied to the

external power supply. RF path requires a dc blocking capacitor.

Exposed Paddle

Exposed Paddle. Internally connected to GND. Solder to a low impedance ground plane.
