High balance over the whole temperature range. Complete differential DC-coupled sign path. It is used for RF sign energy detection, the detection frequency range is 1MHZ - 600MHZ, it's going to come across a RF sign with an influence of -74dBm to 18dBm, and convert the sort of RF sign correct into a output. The larger the amplitude or power of the RF signal, the higher the output voltage, which is proportional to the of the amplitude of the input signal, thus growing the dynamic differ of the detected signal, which reaches 92dB. It can be widely utilized in RF signal detection, signal energy measurement, environmental discipline energy detection, and might even be used as a part of computerized gain leadership and automated point control. Working frequency: 1MHZ---600MHZ Measurement power: -74dBm to +18dBm Output voltage: 0---2 Detection slope: 25mV/dBm (typ.) Input impedance: 50 ohms Supply voltage: 6-15V Type: RF Power Meter Model: AD8307 color:Green Material:Metal Package Contents: 1 x RF Power Meter Only the above kit content, diversified products aren't included. Note: Light and diverse exhibits may cause the color of the thing in the photo barely various from the real thing. The size allowed error is +/- 1-3cm.
