Coupling Devices TRIZ Cases

Aligned windows and metal bridges couple air cavity and ceramic waveguide filters to cut loss, weight, and duplexer complexity.

Built-in phase-adjusting lines create a 180-degree output difference without external shifters, saving PCB area while preserving isolation.

Phase-shift circuits and switchable short-circuit paths help a directional coupler cut main-line loss and block unwanted signal leakage.

Grounded conductive structures beside selected coupled sections suppress parasitic coupling and improve directivity in reflection measurements.

A coupled microwave line sums signals passively at microwave frequencies, cutting circuit complexity, power use, and fabrication cost.

Segmented strip conductors and a bandwidth adjustment part cut output phase errors in a rat-race coupler across frequency bands.

Specific 90° and 180° microstrip phase shifts widen RF divider bandwidth while avoiding the loss and scale penalties of multistage Wilkinson layouts.

A slotted planar hybrid coupler routes E- and H-fields to keep bandwidth constant across frequency scaling while improving RF matching and loss.

A parallel resistor-capacitor branch creates an attenuation pole, helping a magnetically coupled component balance coupling and isolation.

An offset coaxial conductor concentrates field lines toward one ground plane, smoothing microstrip coupling and reducing RF loss and noise.
