5.8GHz RF Power Detector

The S3RFDETISM5G8T18 has been designed for use in high performance wireless communications systems requiring linear measurement of RF power.

The RF power detector measures the power at the RF detector input pins on the IC and outputs a differential voltage signal. It is followed by dedicated differential to single ended converter with driving buffer, optionally this converter could be a multiplexer of two RF detector inputs to one block output.

The detector needs to be calibrated for offset and gain errors and if used in conjunction with a temperature sensor it can be compensated for temperature variation
