Abstract
A high power, non-directional tap coupler having low loss and expanded bandwidth using a novel airline coaxial line structure. Each of the main and secondary conductors forms a concentric structure of constant dimension over a substantial length inside a metallic housing. The coupled port conductor is connected perpendicularly at the middle point to the secondary conductor. The conductors form a novel structure in which coupling remains relatively constant over a broadband frequency range and main line VSWR remains low. The result is a non-directional tap coupler with a wideband operational frequency, a reduced physical size, and low loss and with good PIM performance.
