® w w MAIN PRODUCT CHARACTERISTICS The STPAC01F2 has two outputs, one for the signal detection and another one for the temperature compensation: ■ ■ ■ ■ a D . w S a t IPAD™ e e h U 4 t m o .c STPAC01F2 RF DETECTOR FOR POWER AMPLIFIER CONTROL VDCout = 0.88 V at 0.85 GHz at 10 dBm VDCout = 1.07 V at 1.85 GHz at 10 dBm Vsupply = 5 V max Lead free package DESCRIPTION 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 a temperature information to thermal compensation stage. A biasing stage suppresses the detection diode drop voltage effect.
