APPLICATION NOTES
Input is AC coupled
Output voltage noise increases as RF signal is decreased (due to increasing video gain)
and can be > 500mV with no RF
Response time increases as RF signal is decreased (also due to increasing video gain)
A logging amplifier follows this RF detector. Since the power range covers both the square
law and linear regions of the detector, the transfer curve is not linear with Pin (dB).
However, a smooth relationship exists which can be easily programmed and calibrated.
This detector is accurate for CW signals and will have a different output for signals
containing harmonics or AM levels exceeding about -20 dBc.
