Operating Mode Truth Table Package Drawing Pin Function Description 1V B A T Supply voltage for bias circuitry. 2R F I N 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. 4V M O D E Digital control input for power mode selection (see Operating Modes truth table). 5V E N Digital control input for PA enable and disable (see Operating Modes truth table). 6 CPL_OUT Coupler output. 7G N D 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. 9R F O U T RF output internally matched to 50and 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.

The 50 resistor should be removed if pin 8 is connected to another coupler for daisy chaining multiple couplers. (2). This capacitance value can be reduced for multi-PA with DC to DC converter applications where a total maximum capacitive load is required to be met. Keeping at least a 1uF capacitor close to the PA Vcc pin is recommended. (3). A capacitor of at least 10 nF should be placed closed to the PA VCC pin (pin10) for optimum decoupling.

VCC2S is a sense line to be used if the test power supply has voltage sensing capability. This compensates for any resistive voltage drop that occurs between the power supply and the PA and thus ensures that the voltage at the PA is set as expected.
