  • Patent number: 3965445
    Abstract: An electrical transformer for transforming electrical impedances of high transformation ratios including a dielectric substrate having a pair of parallel electromagnetic coupled-transmission lines bonded to one surface of the dielectric substrate. The first of the pair of transmission lines being adapted to be connected to a first impedance at one end with the other end being connected to a ground terminal through a first tuning capacitance which varies the real part of the transformed impedance. The second of the pair of transmission lines being coupled, at its end opposite the first tuning capacitor, through a second tuning capacitance to a second impedance to which the first impedance is to be matched. The second tuning capacitance is utilized to vary the imaginary part of the transformed impedance.
