STPAC01F1
RF DETECTOR FOR
POWER AMPLIFIER CONTROL
MAIN PRODUCT CHARACTERISTICS
The STPAC01F1 has two outputs, one for the
signal detection and another one for the
temperature compensation:
s VDCout = 0.88 V at 0.85 GHz at 10 dBm
s VDCout = 1.07 V at 1.85 GHz at 10 dBm
s 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.
Target applications are cellular phones and PDA
using GSM, DCS, PCS, AMPS, TDMA , CDMA
and 800MHz to 1900MHz frequency ranges
BENEFITS
s The use of IPAD technology allows the RF
front-end designer to save PCB area and to
drastically suppress parasitic inductances.
