Dec 23, 2020 · Introduction: Millimetre wave frequency ranges power dividers and power combiners are widely used in various microwave applications such as antenna feeds, balanced mixers, balanced amplifiers and phase shifters [1]. The most widely known power divider/combiner is the Wilkinson. It uses a resistor between the quarter-wave …to demonstrate a quarter-wave transformer at 300 MHz. Figs. 2.3(e) and (f) provide templates for two-step and three-step quarter wave transformers for a microwave engineering course. The default values for the line lengths, characteristic impedances and the frequency achieve a good match in these circuits. This is convenientA quarter-wave impedance transformer, often written as λ/4 impedance transformer, is a transmission line or waveguide used in electrical engineering of length one-quarter wavelength (λ), terminated with some known impedance. It presents at its input the dual of the impedance with which it is terminated.

Impedance transformers interface two lines of different characteristic impedance. The smoothest transition and the one with the broadest bandwidth is a tapered line.
