Pin-Out Description
Description
Supply voltage for the bias circuitry.
RF input internally matched to 50 and DC blocked.
Digital control input for power mode selection.
Digital control input for power mode selection.
Digital control input for PA enable and disable.
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 the battery supply or output
of the DC-DC converter.
Ground connection - this 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.
