Default Re: Attenuators - theory and the design of.

Hi Peeps... not that it is VERY technical... but I just put together a 6 pole switched attenuator for my SSB signal generator project, using Teledyne reed relays to switch the steps. It looks reasonably flat to over 150 Mhz..
The resistor values are "near abouts" but I include the table for correct values. All resistors are SMD, and I have just ordered 4700 devices with small graduated steps... to help me hit the correct values.
