Table 1: Pin Description  
PIN  
NAME  
DESCRIPTION  
1
GND  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
RF Input. AC coupled input stage internally matched to 50 Ohms. Route as coplanar  
waveguide using adjacent ground pins.  
2
RFIN  
3
GND  
GND  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
4
Bias Circuit Voltage. Supply voltage and current is applied to this pin to apply power to  
the bias circuits inside the PA.  
5
V
BC  
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.  
6
V
PC  
Detector Bias. Supply voltage and current is applied to this pin to apply power to the  
detector circuits inside the PA.  
7
8
DETDC  
Power Detector Output. DC coupled. An emitter follower BJT supplies the output for  
this pin.  
DETOUT  
9
GND  
GND  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
10  
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.

25  
GND  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
Supply Voltage. Bias for power transistor of stage 3.  
V
V
CC3  
CC2  
Supply Voltage. Bias for power transistor of stage 2.  
GND  
Ground. Connect directly to PCB ground pattern under Pin 25 using short trace.  
Supply Voltage. Bias for power transistor of stage 1.  
V
CC1  
GND  
Ground slug on the underside of the LPCC package.
