RF Coupler Manufacturing Process
RF coupler manufacturing processes
substrate selection
- Fundamental step — determines signal transmission performance and stability.
- Priority: materials with low signal loss, excellent insulation, and high‑temperature resistance.
- Ensures compatibility with subsequent processing, provides a stable carrier, and reduces material‑induced interference.
circuit forming
- Core process — precise forming of RF circuitry onto the substrate.
- Strict control over accuracy and regularity to avoid misalignment or damage.
- Ensures impedance matching, reduces reflection/loss, and guarantees efficient signal coupling.
packaging & assembly
- Protects internal structure, enhances durability and anti‑interference capability.
- Precise fitting of molded circuit to housing; proper seal against dust, moisture, and EMI.
- Extends coupler lifespan and ensures stable operation in complex environments.
testing & calibration
- Final quality gate — uses professional equipment to verify performance.
- Identifies deviations/defects from manufacturing; calibrates parameters to meet specifications.
- Prevents substandard products, guarantees stability and reliability in real applications.
