Device Overview

General Description

The MQH-0517 is a MMIC 5 GHz – 17 GHz quadrature (90°) hybrid. Wire bondable 50Ω terminations are available on-chip. 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. The MQH-0517 is available as a wire bondable chip or connectorized module. Low variation allows for accurate simulations using the provided S4P file taken from measured production units. Applications include single sideband upconverters, image rejection downconverters, IQ modulators, balanced amplifiers, microwave correlators, and microwave Butler matrices.

Typical Performance Plots

Insertion Loss, Return Loss, and Isolation

All measurements taken in a 50Ω environment. Phase balance spread is shown due to large performance spread. Minimal variance observed in amplitude balance and insertion loss. Performance spread is related to packaging and bond wire inductance variation. On-chip load was not used when taking measurements.
