About this product
A logarithmic RF power detector module covering 1 to 8000 MHz that converts the power of an RF signal into a DC voltage. The output voltage follows the signal level in dBm, which suits signal strength indication (RSSI), spectrum analyzer front ends and gain control loops.

- Slope
- –25 mV/dB (typ)
- Output
- DC voltage, logarithmic (dBm)
Frequently asked questions
How do I convert the output voltage to a signal level?
The output is a DC voltage that changes with input power. Use the listed slope of about 25 mV/dB (typ) together with an ADC or meter, and calibrate the offset with a known signal source, since the offset is not given in the listing.
What input level is valid?
The listed dynamic range is -65 dBm to +5 dBm. Signals outside this range are not covered by the listed specifications.
