Abstract
A coplanar strip line compensated balun coupled to a double balanced strip line mixer circuit where the strip lines of the balun have a predetermined radius of curvature and adjusted gap widths to provide for isolation between input and output and for impedance matching over a broad band input. The curvature is adjusted to produce proper inductance for producing input/output isolation. The spacing of the gap width provides for proper capacitive coupling of the transmitted energy between the strip lines since the entire circuit is separated from a ground plane and printed on a lossless dielectric substrate.
