Ground connection.
RF output port for the 802.11a/n LNA. Input is matched to 50Ω 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 Logic Control Table for proper settings.
Not connected.
RF input port for the 802.11a/n PA. Input is matched to 50Ω and DC block is provided.
Not connected.
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.
RF bidirectional antenna port matched to 50Ω and is DC blocked internally.
Ground connection.
Receive switch control pin. See Logic Control Table for proper level.
Control voltage for the LNA. See Logic Control Table for proper settings.
Ground connection.
