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.
