modulator circuit used to indicate low voltage high frequency signal

The voltage doubler circuit of peak rectification shown in the figure is used as test head circuit to control high ohm display loop (field effect voltmeter). Since all the high frequency components adopt very short lead, it can work under high frequency. The lead length can not exceed 2mm, then it can work under VHF area.
