Device Topology & Electromagnetic Behavior
A circular microstrip ring with a circumference of 1.5 guided wavelengths (6 quarter-wave sections). Features characteristic impedance of √2·Z₀ = 70.7 Ω. When driven at Port 1, outputs at Ports 2 and 4 are in-phase; when driven at Port 3, outputs are 180° out of phase. Essential for balanced mixers and monopulse radar.
Rogers RT/duroid® 5870 or 6002 for phase-critical radar applications.
- Center island grounding hole or anti-pad clearance to suppress parallel plate resonance.
- Radius curvature chamfering to prevent discontinuity reflections at port junctions.
