This video describes the design, construction and testing of a basic RF attenuator. The popular PI and T style attenuators are discussed. An example of a 20dB, or 10X, PI attenuator is designed and constructed, and then tested using a spectrum analyzer with tracking generator. The construction technique shown minimized parasitic inductance of the components, thus increasing the usable bandwidth of the attenuator. A copy of the notes in the video can be found here:
