Description
Supply voltage for bias circuitry.
RF input internally matched to 50 and DC blocked. Input matching includes a shunt inductor to ground which
would short DC voltage placed on this pin.
Digital control input for power mode selection (see Operating Modes truth table).
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 amplifier.
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.
