An RF/microwave 3-dB 90 degree coupler is also called a Quadrature (or Quad) Hybrid. It is extremely useful for eliminating reflections, combining amplifiers, for creating I/Q mixers, image reject mixers, and many other applications. Marki Quadrature Hybrids offer excellent phase and amplitude balance across a very broad bandwidth. Additionally the QH-0226 offers a layout with parallel outputs.
