Simple low power RF attenuator
I was after one of the above, and decided to make my own using SMD components and a toner transfer PCB.
It's 0.6dB down at 100Mhz, and 1dB down at 200MHz. In terms of accuracy, I'm getting 1.96dB, 4.17dB, 8.07dB and 15.88dB on each step. I've never built anything RF before so I'm sure it breaks all sorts of best practice, but seems good enough for Government work as they say. |

Re: Simple low power RF attenuator
Looks ok to me. Its all a matter of..is it ok for the uses you are putting it to. If you are wanting Test House Lab results... maybe not.... If its for personal use, you know the limitations, and could adjust if need be. Fine effort .
