Résumé

We have conceived and realized a microwave tunable transformer. The tunability is obtained by loading a transmission line by reverse biased Schottky diodes acting as voltage variable capacitances. Only two diodes pairs are necessary to obtain impedance tunability between 5 Ω to 300 Ω, with an operating frequency varying of more than ± 10 %. Complex loads can also be matched with a wide covering of the Smith chart, but small bandwidth of about 2 %. The device length is around a third of the guided wavelength.
