MAIN PRODUCT CHARACTERISTICS
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.
Target applications are cellular phones and PDA
using GSM, DCS, PCS, AMPS, TDMA , CDMA
and 800MHz to 1900MHz frequency ranges
