Description
Ground connection.
RF output port for the 802.11a/n LNA. Input is matched to 50 and DC block is provided.
Ground connection.
Supply voltage for the LNA. See applications schematic for biasing and bypassing components.
Power detector voltage for TX section. PDET voltage varies with output power. May need external capacitor
for noise decoupling.
Control voltage for the PA and TX switch. See truth table for proper settings.
Not connected.
RF input port for the 802.11a/n PA. Input is matched to 50 and DC block is provided.
Not connected.
Supply voltage for the PA. See applications schematic for biasing and bypassing components.
