BENEFITS RF DETECTOR FOR POWER AMPLIFIER CONTROL WITH INTERNAL TEMPERATURE COMPENSATION IPADTM ■ 0.8 to 2.5GHz frequency range ■ Detection diode voltage drop compensation ■ Temperature compensation ■ Fast response time ■ Low Power consumption ■ Chip Scale device ■ Low parasitic impedance MAIN PRODUCT CHARACTERISTICS 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. DESCRIPTION TM : IPAD is a trademark of STMicroelectronics.
