RF Probe

A RF probe is a handy piece of test equipment that converts a high frequency signal to a DC voltage. In this way it is very easy to measure RF voltages for either testing or adjustment purposes.The RF probe described here is suitable for signals in the frequency range from about 100 kHz to 1000 MHz. Although the diode used here can, in principle, go up to 3 GHz, the impedance of the ground connection will adversely influence the measurement at such very high frequencies.
