RF Step Attenuator

Adjustable attenuation gives precise signal levels

RF Step Attenuator
When dealing with radio-frequency signals it often comes in handy to have an easy way to attenuate a signal level in discrete steps. For example, you might want to reduce the output of an RF generator to a lower level than the output control on the generator allows, and there are many other applications of attenuators in the adjustment and repair of receivers and other radio equipment. Unfortunately professional attenuators are rather pricey, but they do not contain any expensive electronics and so a DIY approach is an eminently practical alternative.
