The Ruthroff Impedance Transformer

Video Description

#209 In this video I look at a Un-un impedance transformer commonly used in various RF circuits. Although it can be built with various impedance ratios and it can work over a wide frequency range, to get the best out of it, it needs to be treated as a transmission line transformers with all of its characteristics.
