Device Topology & Electromagnetic Behavior
An edge-coupled microstrip transmission line pair designed to tap a calibrated fraction of mainline power (e.g., -10 dB, -20 dB, -30 dB) into the coupled port while preserving forward transmission. Used extensively in VSWR monitoring, ALC transmitter feedback, and spectrum test benches.
Rogers RT/duroid® 5880 (εr = 2.20) for low dispersion and minimal dielectric loss.
- Even/odd phase velocity compensation using dielectric overlays or wiggly lines.
- 50 Ω precision thin-film termination on the isolated port.
Design, 3D EM Simulation & Handoff for Directional Coupler (Edge-Coupled)
We provide turnkey synthesis, multi-frequency full-wave simulation, and fabrication-ready packaging for the Directional Coupler (Edge-Coupled).
1. 3D Full-Wave FEM Modeling
