Marki Microwave surface mount quad splitters provide broadband splitting of a signal into equal-amplitude in-phase (0�) and quadrature (90�) outputs. These devices are non-reciprocal and designed to operate with specific input ports, as driving alternate ports can degrade phase balance and performance. They offer excellent phase and amplitude balance across broad bandwidths and are ideal for applications such as balanced amplifier combining, balanced mixer drive, image-reject architectures, interference cancellation, and single-sideband systems.
