Can anyone suggest me RF power log detector with following specifications
1. Input frequency range 500M to 10GHz
2. Input power dynamic range 40dB
3. with ±0.5 db accuracy (This is the most important parameter for me)
4. Most prefer one +ve slop detector.
5. Slop should be > 30mV/db
I want to detect RF power with ±0.5 db accuracy over -20 to +55º C temperature range.
Anyone can suggest me the better method to measure it.
You might consider AD8317 or AD8319. Slope magnitude and polarity are not what you want, but that's easily fixed with an output op amp.
