MQH-40110M2_MMIC 40-110GHz Quadrature Hybrid

Device Overview

General Description

The MQH-40110M2 is a 40–110 GHz quadrature (90°) hybrid in our miniature M2-package enabling operation up to 110 GHz. The quad hybrid features exceptional amplitude and phase balance and high isolation between the quadrature ports. Passive GaAs MMIC technology allows production of smaller constructions that replace larger form factor circuit board constructions. Tight fabrication tolerances allow for less unit-to-unit variation than traditional quadrature hybrid technologies. Low variation allows for accurate simulations using the provided S4P file taken from measured production units. The MQH-40110M2 is available as a 1.0mm connectorized module.
