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.
BenefitS
■ The use of IPAD technology allows the RF front-end designer to save PCB area and to drastically suppress parasitic inductances.
