摘要：A high power, TEM mode directional microwave coupler having low loss andexpanded bandwidth uses novel thick suspended substrate conductors to provide multi-octave bandwidth performance in a practical package. Each of two center conductors isformed using metal layer deposited onto three surfaces of a thick dielectric substrate.The conductors, which can be edge-coupled or offset-coupled, form a novel structure inwhich the non-metallized side of the substrate is oriented toward the facing outsidevertical walls. This effectively reduces the effect of the package wall on the couplingstructure, permitting a smaller, constant-width dimension, which in turn raises thewaveguide cut-off frequency. The result is a directional coupler with an extended highfrequency performance, with reduced physical size and low loss.
