RFCM3328 Temperature Sensing Feature

The RFCM3328 provides an internal NTC resistor for temperature sensing. This resistor is located right next to the output

transistor stage. Within the application circuit the NTC is part of a voltage divider. The output voltage of the voltage divider

(Vt) can be correlated to the module backside temperature.
