Description

VBIAS

Bias: Internal DC bias. This pin should be connected to VPOS

through a 3.3K

Ω resistor for optimum performance

RFIN

RF Input: Input to LNA

3,4,5,6

NC: No internal connection

RFOUT

RF Output: Must be AC-coupled.

VPOS

Supply: VDD bias needs to be bypassed to ground using

low-inductance capacitors. The recommended

configuration is for the output matching to be done on this

pin. See schematics in applications section.

Exposed pad

Exposed Paddle: Connect to a low impedance ground plane
