Description
RF input for the 802.11b/g/n PA. Input is matched to 50 and DC block is provided.
Ground.
RF bidirectional port for Bluetooth. Input is matched to 50 and DC block is provided.
Digital enable pin for the 802.11b/g/n PA. This is an active high control. An external bypass capacitor may be
needed on the PA EN line for decoupling purposes.
Supply voltage for the 802.11b/g/n PA.
Supply voltage for the 802.11b/g/n PA.
Linearity and Efficiency control pin, please see the Theory of Operation for more information.
Power detector voltage for Tx section. PDET voltage varies with output power. May need external decoupling
capacitor for module stability. May need external circuitry to bring output voltage to desired level.
