Connect directly to PCB ground pattern under Pin 25 using short trace. 5 V BC Bias Circuit Voltage. Supply voltage and current is applied to this pin to apply power to the bias circuits inside the PA. 6 V PC Power amplifier power control pin. The recommended use is for on/off control of the PA. Nominally, 0 V applied will turn amplifier completely off; +3.3 V should be used to set amplifier to maximum output capability. A series resistor is used to set the current flow into the pin, thereby controlling the overall bias level of the PA. 7 DETDC Detector Bias. Supply voltage and current is applied to this pin to apply power to the detector circuits inside the PA. 8 DETOUT Power Detector Output. DC coupled. An emitter follower BJT supplies the output for this pin. 9 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. 10 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. 11 RFOUT RF Output. AC coupled output stage internally matched to 50 Ohms. Route as coplanar waveguide using adjacent ground pins. A shunt inductive matching element included inside the PA after the AC coupling capacitor provides a DC path to ground at this pin. 12 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. 13 VCC3 Supply Voltage. Bias for power transistor of stage 3. 14 VCC2 Supply Voltage. Bias for power transistor of stage 2. 15 GND Ground. Connect directly to PCB ground pattern under Pin 25 using short trace. 16 VCC1 Supply Voltage.
