Device Topology & Electromagnetic Behavior

Splits an input signal into two equal-amplitude, equal-phase outputs. Incorporates an internal isolation resistor (2·Z₀ = 100 Ω) between the two output quarter-wave arms (√2·Z₀ = 70.7 Ω) to dissipate reflected mismatch power and achieve >25 dB port-to-port isolation.

ANALYTICAL FORMULATIONS & S-MATRIX MAPPING
Z_arm = √(2) · Z₀ ≈ 70.71 Ω (Length = λ_g / 4)
• Quarter-wave impedance transformation arms matched to 50 Ω system.
R_iso = 2 · Z₀ = 100 Ω
• Isolation resistor absorbs odd-mode reflected power between Port 2 and Port 3.
Recommended Substrate Stackup

Rogers RT/duroid® 5880 (εr = 2.20) for minimal dielectric loss; RO4350B (εr = 3.66) for rigid low-cost commercial boards.

Nikola RF Fabrication Directives
  • Thin-film or 0402 low-parasitic surface mount isolation resistor.
  • Mitered 90° bends to reduce parasitic capacitance at T-junction.
  • Stitched ground via fences surrounding split ports for >70 dB chassis isolation.
