Using Baluns and RF Components for Impedance Matching

WebAug 12, 2014 · Experiments have shown that efficiency, at least with the Ruthroff unun, decreases as the impedance level increases. With Guanella’s approach, each transmission line shares a portion of the load; therefore, his transmission lines can work at lower impedance levels. Also, the longitudinal gradients are less with his transformers. WebThis paper presents a Ruthroff type spiral un-to-un transmission-line transformer (TLT) with impedance transformation ratio of 4:9.

WebEarly work by the author has shown that the tapped-Ruthroff 1:4 transformer can yield low-impedance designs under certain conditions. Their designs and limitations are included in this chapter. More recent work by the author has shown that, by far, a better technique is to use higher-order windings with the Ruthroff "bootstrap" method.

WebCoilcraft wideband RF Transformers provide a wide range of impedance ratios and frequency bandwidths for use as baluns and for impedance matching. The complete … WebSince Ruthroff's transformers summed a delayed voltage with a direct voltage, his transformers had a built-in, high-frequency cut-off. Although his transformers don't have the inherent high-frequency response of Guanella's transformers (which sums voltages of equal delays), they are easier to construct and many of his ununs should find use in matching …
