Pin Configuration and Description

Pin No.

Label

Description

1, 3, 4, 5, 8

NC

No electrical connection. Provide grounded land pads for PCB mounting integrity.

2

RF In

RF Input pin. A DC Block is required.

6

Shut Down

A high voltage(>1.17V) turns off the device. If the pin is pulled to ground or driven

with a voltage less than 0.63V, then the device will operate under LNA ON state.

7

RF Out / DCBias

RF Output pin. DC bias will also need to be injected through an RF bias

choke/inductor for operation.

Backside

Paddle

RF/DC GND

RF/DC ground. Use recommended via pattern to minimize inductance and thermal

resistance; see PCB Mounting Pattern for suggested footprint.
