This pin is not connected internally and can be left floating but is recommended to connect to ground.
Supply voltage for the PA. See applications schematic for biasing and bypassing components.
Supply voltage for the PA. See applications schematic for biasing and bypassing components.
Ground Connection. This pin is not connected internally and can be left floating or connected to ground.
RF input port for the 802.11a/n/ac PA. Input is matched to 50Ω and DC blocked internally
Ground Connection. This pin is not connected internally and can be left floating or connected to ground.
Control voltage for the PA. See “Switch Control Truth Table” for proper settings.
No Connect. This pin is not connected internally and can be left floating or connected to ground.
Supply voltage for the LNA, Switch & Bias Regulator. See applications schematic for biasing and bypassing components.
Ground Connection. This pin is not connected internally and can be left floating or connected to ground.
RF output port for the 802.11a/n/ac LNA. This port is matched to 50Ω and DC blocked internally.
Control voltage for the LNA. When this pin is set to a LOW logic state, the bypass mode is enabled.
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”)
Ground Connection. This pin is not connected internally and can be left floating or connected to ground.
RF bidirectional antenna port matched to 50Ω.
Ground Connection. This pin is not connected internally and can be left floating or connected to ground.
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.
