Device Topology & Electromagnetic Behavior
A planar microwave Marchand balun composed of coupled line sections that transforms an unbalanced 50 Ω input into a balanced 100 Ω differential output pair with exact 180° phase opposition and zero common-mode leakage. Critical for feeding dipole antennas, log-periodic arrays, and double-balanced mixers.
Rogers RT/duroid® 6010.2LM (εr = 10.2) for tight coupled line spacing and size reduction.
- Strict symmetry across the longitudinal center axis to minimize amplitude/phase unbalance.
- Broadside coupled stripline topology for ultra-tight coupling in multi-layer stackups.
