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.
