Receive port for 802.11b/g/n band. Internally matched to 50Ω. 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.
RF input for the 802.11b/g/n PA. Input is matched to 50Ω. DC block required.
Supply voltage for the FEM. Power down pin. Apply <0.6 VDC to power down the power amplifier stages. Apply
2.5 VDC to 3.6 VDC to power up. If function is not desired, pin may be connected to VCC or VREG.
Supply voltage for the FEM.
Power detector voltage for TX section. PDET voltage varies with output power. May need external decoupling.
Port matched to 50Ω. DC block required.
Ground connection.
Bluetooth® RF Port. DC block required.
Control pin for WiFi Receive Port. Please see truth table for proper settings.
Control pin for Bluetooth® Port. Please see truth table for proper settings.
Control pin for WiFi Transmit Port. Please see truth table for proper settings.
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.
