Description
RF input for the 802.11b/g/n PA. Input is matched to 50. DC block required.
Regulated voltage for the PA bias control circuit. An external bypass capacitor may be needed on
the VREG line for decoupling purposes.
Receive port for 802.11b/g/n band. Internally matched to 50. DC block required.
Control pin for WiFi Transmit Port. See truth table for proper settings.
Control pin for Bluetooth® Port. See truth table for proper settings.
Control pin for WiFi Receive Port. See truth table for proper settings.
Bluetooth® RF Port. DC block required.
Ground connection.
Antenna port matched to 50. DC block required.
Power detector voltage for TX section. P_DET voltage varies with output power. May need external
decoupling.
Supply voltage for the FEM. See applications schematic for biasing and bypassing components.
Same as pin 11.
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.
