  • High frequency impedance transformer
    Patent number: 5774026
    Abstract: A coupling and matching device for high frequency or microwave signal transmission includes two line sections (9, 10) with parallel, weakly coupled portions (9', 10'), where the primary section (9) forms a short circuit and is connected to a relatively low output impedance device while the secondary section (10) is connected to a relatively high input impedance device. The coupling and matching device also includes a ground plane parallel to the secondary line section (10), and a member (12) for varying the difference between the secondary line section and the ground plane.
