N/C

No connection necessary.

These pins may be connected to RF/DC ground.

2

RF IN

This pin is matched to 50 Ohms with a 19 nH inductor to

ground. See Application Circuit.

4

Vctl

DC ground return. LNA is in high gain mode when a short

circuit is introduced to this pin through an external switch.

LNA is in bypass mode when open circuit is introduced

6ACG

An external capacitor of 0.01µF to ground is required

for low frequency bypassing.

See Application Circuit for further details.

7, 14

GND

These pins must be connected to RF/DC ground.

9

Vdd

Power supply voltage. Choke inductor and bypass capacitor

are required. See application circuit.

11

RF OUT

This pin is AC coupled and matched to 50 Ohms.
