#244 In this video I look at a wider bandwidth implementation of the quarter wavelength impedance transformer - the stepped impedance transmission-line transformer. In essence its a series of multiple quarter wavelength transformers, one is series with the other, which brings a very interesting propriety - the total bandwidth increases.
