Hello everyone!
Today I measured the RF power range by using the bi-directional coupler for my project 'Return loss measurement using RF sensor as 50-ohm load). The block diagram of my project is attached below:
I measured both of the RF power ranges with the 20dB bi-directional coupler and the numbers are attached below:
The next step for me is to select an RF Power Detector. I need to RFPDs, each handling the coupled powers (incident and reflected) and converting it to an analog voltage.
I have seen that there are three types of RFPDs:
1. Peak or envelop Detector
2. Log Detector, and
3. RMS detector
I need an analog voltage continuously being detected by RFPDs from -35dBm to -7dBm (around 2.8mV to 71mV). Which RF Power Detector shall I use from the above mentioned? According to some research, Peak detector seems a better option. But, I also want some comments from you guys.
Thanks!
