Description  
Coupler  
VBIAS  
The STPAC01F2 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  
RF input
