Function

Description

Interface Schematic

1NC

No connection. This pin should be connected to the ground plane.

2NC

Same as pin 1.

3GND

Ground connection. Keep traces physically short and connect immedi-

ately to ground plane for best performance. Each ground pin should

have a via to the ground plane.

4GND

Same as pin 3.

5GND

Same as pin 3.

6RF IN

RF input pin. This pin is not internally DC blocked. A DC blocking

capacitor suitable for the frequency of operation is required if DC is

present from the previous stage. The gate voltage is nominally 0V but

can be raised externally to increase the bias level. This will increase the

current drain but improve linearity.

7NC

Same as pin 1.

8NC

Same as pin 1.

9NC

Same as pin 1.

GND

Same as pin 3.

GND

Same as pin 3.

RF OUT

RF output and bias pin. Because DC is present on this pin, a DC block-

ing capacitor, suitable for the frequency of operation, should be used in

most applications. For biasing, only an RF choke is needed.

Same as pin 1.
