Pin Names and Descriptions

Pin

Name

Description

1

NC

This pin is not connected internally and can be left floating but is recommended to connect to ground.

2

VCC2

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

3

VCC1

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

4

GND

Ground Connection. This pin is not connected internally and can be left floating or connected to ground.

5

TX

RF input port for the 802.11a/n/ac PA. Input is matched to 50Ω and DC blocked internally

6

GND

Ground Connection. This pin is not connected internally and can be left floating or connected to ground.

7

PA_EN

Control voltage for the PA. See “Switch Control Truth Table” for proper settings.

8

GND

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

9

VBAT

Supply voltage for the LNA, Switch & Bias Regulator. See applications schematic for biasing and bypassing components.

10

GND

Ground Connection. This pin is not connected internally and can be left floating or connected to ground.

11

RX

RF output port for the 802.11a/n/ac LNA.

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

12

LNA_EN

Control voltage for the LNA. When this pin is set to a LOW logic state, the bypass mode is enabled.

13

SW_CTL

Switch control voltage. High control voltage turns ON the TX path and low control voltage turns on the RX path (see

“Switch Control Truth Table”)

14

GND

Ground Connection. This pin is not connected internally and can be left floating or connected to ground.

15

ANT

RF bidirectional antenna port matched to 50Ω.

16

GND

Ground Connection. This pin is not connected internally and can be left floating or connected to ground.

Pkg Base

GND

Ground connection. The backside of the package should be connected to the ground plane through a short path, i.e., PCB

vias under the device are recommended.
