Pin Descriptions
Pin
Name Description
1
NC*
No Connect. This pin is not connected internally. It can be left floating or connected to ground.
2
VCC
Supply voltage for the PA. See applications schematic for biasing and bypassing components.
3
VCC
Supply voltage for the PA. See applications schematic for biasing and bypassing components.
4
NC*
No Connect. This pin is not connected internally. It can be left floating or connected to ground.
5
TXIN
RF input port for the 802.11a/n PA. Input is matched to 50Ω. Internally DC blocked.
6
NC*
No Connect. This pin is not connected internally. It can be left floating or connected to ground.
7
PAEN
Control voltage for the PA. High PAEN enables the PA and Low PAEN disables the PA (see switch logic tables).
8
NC*
No Connect. This pin is not connected internally. It can be left floating or connected to ground.
9
VCC
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.
