Feature: 1. It can detect a RF signal of power from -55dBm to 0dBm, and convert the RF signal into a DC voltage output. 2. The higher radio frequency signal range or power is, the higher output voltage will be, and output voltage is proportional to logarithm of input signal range. 3. Widely used for RF signal detection, signal power measurement, environment field strength detection. 4. Provide accurate R F measurement. The measurement accuracy in the dynamic range greater than 50dB is better than ± 1dB. The output has the function of power controller when adjusting the power amplifier or variable gain amplifier. 5. It provides better precision and temperature stability in a temperature range of 40 ~ C ~ + 85 ℃, and has a fast output response of 5ns, which can achieve R F pulse string detection of more than 125 MHz. 6. The device has a shielded case and anti-reverse protection diode function in the 3V ~ 5V power supply voltage range.
