Operating Mode Truth Table Package Drawing Pin Function Description 1 VBAT Supply voltage for bias circuitry. 2 RF IN 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. 3N C No connection. 4 VMODE Digital control input for power mode selection (see Operating Modes truth table). 5 VEN Digital control input for PA enable and disable (see Operating Modes truth table). 6 CPL_OUT Coupler output. 7 GND This pin must be grounded. 8 CPL_IN Coupler input used for cascading couplers in series. Terminate this pin with a 50 resistor if not connected to another coupler. 9 RF OUT RF output internally matched to 50 and DC blocked. 10 VCC Supply voltage for the first and second stage amplifiers, which can be connected to battery supply or output of DC-DC converter. Pkg Base GND 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.
