RF DETECTOR FOR  
POWER AMPLIFIER CONTROL  
IPADTM  
MAIN PRODUCT CHARACTERISTICS  
The STPAC01F1 has two outputs, one for the  
signal detection and another one for the  
temperature compensation:  
VDCout = 0.88 V at 0.85 GHz at 10 dBm  
VDCout = 1.07 V at 1.85 GHz at 10 dBm  
Vsupply = 5 V max.  
DESCRIPTION  
The STPAC01 is an integrated RF detector for the  
power control stage. It converts RF signal coming  
from the coupler into a DC signal usable by the  
digital stage. It is based on the use of two similar  
diodes, one providing the signal detection while  
the second one is used to provide a temperature  
information to thermal compensation stage. A  
biasing stage suppresses the detection diode drop  
voltage effect.

BENEFITS  
The use of IPAD technology allows the RF  
front-end designer to save PCB area and to  
drastically suppress parasitic inductances.
