QL-Custom RF Connector Adapter Solutions
Comprehensive selection of RF adapters for seamless connectivity between different connector types, genders, and configurations.
Why Choose QL-Custom RF Adapters?
We don’t just machine adapters – we engineer signal continuity. Whether you need to bridge between a quick‑connect BNC and a threaded N‑Type, or convert reverse‑polarity SMA to standard TNC, our adapters maintain characteristic impedance (50Ω or 75Ω) and minimize interface reflection. Every adapter is verified with a vector network analyzer before shipping.
We perform 100% insertion loss and VSWR tests across the entire operating frequency range, not just spot checks. Our in-house plating line ensures consistent contact resistance and corrosion resistance for every adapter. For custom or hard-to-find combinations, we provide full mechanical drawings and RF test reports with every shipment.
