Description
Supply voltage for bias circuitry.
RF input internally matched to 50 and DC blocked. The RF input matching circuit has a shunt inductor to
ground which would short any DC voltage placed on this pin.
No connection.
Digital control input for power mode selection (see Operating Modes truth table).
Digital control input for PA enable and disable (see Operating Modes truth table).
Coupler output.
This pin must be grounded.
Coupler input used for cascading couplers in series. Terminate this pin with a 50 resistor if not connected to
another coupler.
RF output internally matched to 50and DC blocked.
Supply voltage for the first and second stage amplifiers, which can be connected to battery supply or output of
DC-DC converter.
Ground connection. The package backside should be soldered to a topside ground pad connecting to the PCB
ground plane with multiple ground vias. The pad should have a low thermal resistance and low electrical imped-
ance to the ground plane.
