Learn More About Hybrids

A quadrature or 90˚ hybrid is a special type of power splitter that creates a 90˚ (π/2 radians) phase shift between the two outputs. This phase shift is both broadband (unlike a delay line) and relative (between the outputs). Marki quadrature hybrids are created by building a backwards wave coupler (similar to our stripline directional couplers) with a 3 dB coupling value and creating equal power outputs (for other methods and their merits or demerits, see this tech note). Important figures of merit include amplitude balance, phase balance, and isolation between output ports. Among the many applications of quadrature hybrids are balanced amplifiers and the quadrature signal generation necessary for IQ and image reject mixers.

90° Surface Mounts

A hybrid is a coupler that behaves as a power divider, providing an equal power split from input to output while creating a broadband 90° phase shift between the two outputs. Our MQS quadrature splitters are MMIC solutions that provide high performance in a very small form factor.
