Anybody how to build one using a gual gate fet and a diode detector. Freq rance 0-500 MHz.
I'm thinking to make a tap at the output and feed it to the diode to get a DC voltage, then maybe add an op-amp or two or maybe make a summing amp which should control the gain of the fet.
I'm using BF980 for the fet.
Appreciate any suggestions.
