DuWayne KV4QB, has done a Step Attenuator project and was kind enough to give me a board he designed for it at FDIM this year. So, I will not reinvent the wheel here and follow his design. Thank you DuWayne. Here’s a link to his blog where you can read not only about his attenuator project but other great things he has done. kv4qb.blogspot.com
As is with DuWayne’s project, I’ll use 2 pe4302 boards connected in series with the control lines in parallel. This will mean that the attenuator steps will be in 1dB increments which is fine for anything I’ll require. Max power input is +24dbm which is again fine for my purposes.
