Digital Active Rf Detector Probe Circuit Diagram

This is a Digital Active Rf Detector Probe Circuit Diagram. An MFP102 FET is used as a wideband amplifier. LI can be 100 for 30 to 100 MHz or 1000 for 2 to 30 MHz. For LF, (less than 3 MHz), use a 2,5- RF choke. This probe will work as a relative indicator device, but it can be calibrated over a frequency range, if needed.
