The detector is is used for RF signal power detection of frequency range between 1MHZ and 600MHZ.
It can detect a rf signal of power from -74dBm to 18dBm, and convert the RF signal into a DC voltage output.
The higher radio frequency signal range or power is, the higher output voltage will be.
output voltage is proportional to logarithm of input signal range.
Widely used for RF signal detection, signal power measurement, environment field strength detection, can also be used as a part of automatic gain control and automatic level control.
It can be made into 1mw ~ 1kw RF power meter after appropriate transformation.
