Pin Descriptions

Pin

Name

Description

1NC*

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

2VCC

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

3VCC

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

4NC*

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

5TXIN

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

6NC*

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

7PAEN

Control voltage for the PA. High PAEN enables the PA and Low PAEN disables the PA (see switch logic tables).

8NC*

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

9VCC

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

10

NC*

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

11

RX

Receive (Rx) 50Ω output pin.

12

NC*

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

13

VTX

Switch control voltage. High control voltage turns on the Tx path and low control voltage turns on the Rx path

(see switch logic tables).

14

NC*

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

15

ANT

RF bidirectional antenna port matched to 50Ω.

16

NC*

No Connect. This pin is not connected internally. It 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;

PCB vias under the device are recommended.

* It is recommended to ground all NC pins.
