RF Probe Circuit


Posted on Feb 6, 2014

A RF probe is a circuit for testing equipment that converts a high frequency signal into a DC voltage. In this way it is very easy to measure RF voltages for either testing or adjustments of transmitters, receivers, modulators. The RF probe circuit described here is suitable for signals with the frequency range from about 100 kHz to 1000 MHz. Alth

ough the diode used here can, in principle, go up to 3 GHz, the impedance of the ground connection will adversely influence the measurement at very high frequencies. Also, please keep in mind to use this probe only on low RF power.
