Yes, I was too busy to go get my schematics out.? I bought 10 from eBay.? Don't know if they are real ones?

I have them on one of my boards, seem to work OK.

There are more (newer) models now.? But expensive buying from a distributor.

Are you referring to the AD-8307 ??

You can buy the wattmeter IC on eBAY or buy the whole board.? I don't
remember, AD?

I think I got the IC for about $1.?? I got it to track fairly well from
0 to -40 dBm.

I was using an HP function generator at 10 MHz.?? Nice, you can dial in
dBm directly.


You would have to make a pi or t pad in front of them.? Reduce the power.

I used the Arduino to read them.

The info is on the net.? Search eBay too.

on this item or maybe available as a kit??

Or, how about 150W DL with builtin wattmeter for under $20? This was
a build our group did a couple of months ago. The lid is shown here.
The resistor network sits in a mineral oil bath. The downside is that
this is considerably larger than yours and a little more expensive.
