Pin Names and Descriptions
Pin
Name
Description
1
PDET
Power detector voltage for the TX path. May need external series R and/or shunt C to adjust voltage level and
to filter RF noise
2
NC*
No Connect. This pin is not connected internally and can be left floating or connected to ground.
3
VCC
Supply voltage for the output stage of the PA. See applications schematic for biasing and bypassing
components.
4
VCC
Supply voltage for the first stage of the PA. See applications schematic for biasing and bypassing
components.
5
TX
RF input port for the 802.11b/g/n PA. Input is matched to 50Ω. An external DC block is required.
6
PA_EN
Bias voltae for the PA. This pin also controls the TX switch of the SP3T. See truth table for proper settings.
7
NC*
No Connect. This pin is not connected internally and can be left floating or connected to ground.
8
RX
RF output port for the 802.11b/g/n LNA. Port is matched to 50Ω. An external DC block is required.
9
LNA_EN
Control voltage for the LNA. When this pin is set to a LOW logic state, the bypass mode is enabled.
10
VCC
Supply voltage for the LNA. See applications schematic for biasing and bypassing components.
11
BT
RF bidirectional port for Bluetooth®. Input is matched to 50Ω. An external DC block is required.
12
NC*
No Connect. This pin is not connected internally and can be left floating or connected to ground.
13
C_BT
Bluetooth® switch control pin. See truth table for proper level.
14
C_RX
Receive switch control pin. See switch truth table for proper level.
15
NC*
No Connect. This pin is not connected internally and can be left floating or connected to ground.
16
Pkg Base
ANT
GND
RF bidirectional antenna port matched to 50Ω. An external DC block is required.
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.
