Abstract: A miniaturized multi-sectioned, directional coupler using a multi-layer MMIC process, the coupler comprising, a monolithic microwave integrated circuit, having a central section with a relatively tight coupling, surrounded by sections of lighter coupling, the relatively tight coupling being comprised of a pair of spiral coupled lines, and the lighter coupling being comprised of meandered edge couple lines with capacitive loading of the lines in several places.

Abstract: A MMIC amplifier is directly connected to the balanced feed points at the aperture of an antenna to eliminate the distance between electronics coupled to the antenna and the antenna itself, such that interfaces, components and connection lines which introduce losses and parasitic effects that degrade system performance are eliminated due the direct connection. Expanding the aperture of the antenna to accommodate the direct connection of a MMIC amplifier to balanced feed points of an antenna has been found to have no deleterious effects on antenna performance. Moreover, when coupling the MMIC amplifier to an unbalanced coaxial line, any associated ripple is minimized due to the direct connection.
