High stability over the entire temperature range. Complete differential DC-coupled signal path. It is used for RF signal detection, the detection frequency range is 1MHZ - 600MHZ, it can detect a RF signal with a of -74dBm to 18dBm, and convert such a RF signal into a output. The greater the amplitude or of the RF signal, the higher the output voltage, which is proportional to the logarithm of the amplitude of the input signal, thus expanding the dynamic range of the detected signal, which reaches 92dB. It can be widely used in RF signal detection, signal measurement, environmental field strength detection, and can also be used as a component of automatic gain control and automatic level control. Working frequency: 1MHZ---600MHZ Measurement : -74dBm to +18dBm Output voltage: 0---2.5V Detection slope: 25mV/dBm (typ.) Input impedance: 50 ohms Supply voltage: 6-15V Type: RF Meter : AD8307 color:Green Material:Metal Package Contents: 1 x RF Meter Only the above package content, other products are not included. Note: Light and different displays may the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
