HIGH PERFORMANCE, LOW COST, SURFACE-MOUNT QUADRATURE COUPLERS

摘要

As system requirements increase, the demands placed on passive components also continue to rise in an effort to meet ever-increasing consumer demands. Industry is demanding higher performance in smaller footprints at a lower cost. Current quadrature coupler offerings suffer from various drawbacks such as narrow bandwidth and limited selection in the case of GaAs-based products, poor repeatability for core- and wire-based products, and large size and leadless surface-mount package styles for other types.
