DESCRIPTION
The STPAC02F1 is an integrated RF detector for
power control chain. It has been developed to
convert the RF signal coming from the external
coupler into a DC signal usable by the mobile
digital stage. It is based on the use of two similar
diodes, one assuming the signal detection while
the second one is used to compensate the ambient
temperature effect. A biasing stage suppresses
the detection diode drop voltage effect. The use of
the IPAD technology allows the RF front-end
designer to save PCB area and to drastically
suppress the parasitic inductances of the package.
Target applications are cellular phones and PDA
using GSM, DCS, PCS, AMPS, TDMA , CDMA
and 800MHz to 2100MHz frequency ranges
.
