Description

1

VBIAS

Internal DC Bias. This pin should be connected to VPOS through the R1 resistor.

2

RFIN

RF Input. This is the input to the LNA.

3, 4, 5, 6 NC

No Connection. No internal connection.

7

RFOUT

RF Output.

8

VPOS

Supply Voltage. DC bias needs to be bypassed to ground using a low inductance capacitor. This pin is

also used for output matching. See the Basic Connections section.

9 (EPAD) Exposed Pad (EPAD) GND. Connect the exposed pad to a low impedance ground plane.
