Device Topology & Electromagnetic Behavior
A 3-port frequency-selective network joining a low-pass (or low-band BPF) channel and a high-pass (or high-band BPF) channel at a common junction. Allows dual-band transmitters (e.g., 2.4 GHz and 5.8 GHz, or Sub-6 GHz and mmWave) to share a single coaxial cable or dual-band antenna with >35 dB cross-band isolation.
Rogers RT/duroid® 5880 for minimal passband insertion loss.
- Impedance-matched junction manifold to prevent standing wave ripple at cross-over frequencies.
- Comprehensive ground via-fence separation between low-band and high-band filter arms.
Design, 3D EM Simulation & Handoff for Dual-Channel Diplexer
We provide turnkey synthesis, multi-frequency full-wave simulation, and fabrication-ready packaging for the Dual-Channel Diplexer.
1. 3D Full-Wave FEM Modeling
Complete Ansys HFSS 3D CAD modeling with true edge-launch SMA or SMP connectors, via fence stitching, and adaptive mesh refinement down to ΔS < 0.007.
2. Sensitivity & Tolerance Sweeps
Monte Carlo statistical analysis over copper etching tolerances (±15 µm) and substrate permittivity variations to guarantee first-pass high-yield manufacturing.
3. Manufacturing Handoff
Delivery of verified simulation models, parameterized layout geometries, and photolithography-compliant Gerber RS-274X fabrication packages.
