Rf Power Meter Circuit

This circuit is another radio frequency rf field strength meter similar with our previous field strength meter circuit but with lower supply voltage only a single cell 1 5v battery. Although you might consider the ic as slightly expensive at about 10 in single quantities its cost is justified by the wide dynamic range and outstanding accuracy offered. The circuit diagram of the decibel meter in figure 1 stands out by its simplicity which is due to the type ad8307 monolithic demodulating logarithmic amplifier ic1 from analog devices.
