The Mysterious 50 Ohm Impedance: Where It Came From and Why We Use It 50 Ohm impedance became the standard impedance used in RF transmission lines long ago, but it is still useful today and is a standard reference impedance used in test equipment. Read Article

S-Parameter Measurements and Errors in Power Integrity No matter where you look, it seems S-parameters never go away! They are mandatory tools for understanding some systems, such as an interconnect or antenna, while other network parameters can sometimes give a better conceptual understanding of electrical behavior. These parameters are normally reserved for signal integrity among electronics engineers, but if you look hard enough, you’ll find that S-parameters are also used for power integrity Read Article
