RF To DC COnverter - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

I have a VHF & UHF TV Transmitters which produce 500W. I run this through bi-directional coupler. I need a circuit that will take RF signal in VHF & UHF band and produce 0 to10 VDC adjustable. Any ideas or sources.

Thank you very much

Good day. Check out both Analog Devices and Linear Technology. I believe they both make an IC that does RF to DC. They might not have the DC voltage range that you want, but you should be able to scale it.

Good Luck
Michael

I designed a similar circuit using a Analog Device's AD8010. You will need to couple >60db from your signal. You will have to scale the output.

It seems the detector is the easy part of this circuit, what are you going to use for a coupler?

A correction to my previous post, I used an Analog Device part AD8310.
