Rf Power Meter Circuit

Here is the schematic diagram of this rf strength meter circuit.

Rf power meter circuit.

A tap circuit supplements the power meter extending the upper limit by 40 db allowing measurement of up to 100 w 50 dbm. Here is yet another ad8307 based rf power meter which adds an opamp to produce a dc output voltage of 1mv dbm e g 0mv 0dbm 10mv 10dbm etc. The rf power in dbm can be read directly with a multimeter and i ve found it particularly useful for measuring rf filter response when combined with a sweep generator and an oscilloscope. The power meter the cornerstone of the power meter circuit shown in figure 1 is an analog devices ad8307an logarithmic amplifier ic u1.

Rf power meters or wattmeters are used for measuring power in rf circuits. Although you might consider the. Power can be measured in a variety of ways dependent upon the application. Adjust c1 for peak reading.

Rf decibel power meter description. To use turn on transmitter and meter. Rf power meter pep average pulse power power measurement techniques in line power meter absorption power meters sensors. The measurand quantity to be measured is applied to pin 8 inp of ic1 via input socket k1 and capacitor c1.

Rf microwave power meter includes. 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.
