Description

1

RFIN

RF input port for the PA. This port is matched to 50Ω and DC shorted internally.

2

PA_EN

Control voltage.

3

GND

Ground connection.

4

VCC

Supply voltage. See applications schematic for biasing and bypassing components.

5

GND

Ground connection.

6

GND

Ground connection.

7

PDET

Power Detector voltage for the PA. May need external series R/shunt C to adjust voltage level and to

filter RF noise.

8

NC

No connect. This pin is not connected internally and can be left floating or connected to ground.

9

GND

Ground connection

10

RFOUT

RF output port.

This port is matched to 50Ω and DC blocked internally.

11

RFOUT

RF output port.

This port is matched to 50Ω and DC blocked internally.

12

GND

Ground connection

13

VCC2

Supply voltage. See applications schematic for biasing and bypassing components.

14

NC

No connect. This pin is not connected internally and can be left floating or connected to ground.

15

VCC1

Supply voltage. See applications schematic for biasing and bypassing components.

16

GND

Ground connection

Backside

Paddle

GND

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

PCB Mounting Pattern for suggested footprint.
