High-Frequency RF Coaxial Connector

Product Specifications

Technical details and manufacturing context for High-Frequency RF Coaxial Connector

Definition

The High-Frequency RF Coaxial Connector is a precision interconnect component used in the manufacture of communication equipment. It is designed to transmit radio frequency signals with controlled impedance, ensuring minimal signal loss and reflection at microwave frequencies. This connector is typically employed in devices such as routers, base stations, and wireless equipment, where it provides reliable connections between circuit boards, antennas, and modules. Its standardized design facilitates modular assembly and simplifies supply chain integration for B2B customers.

The connector features concentric conductors separated by a dielectric material to maintain a characteristic impedance of 50 Ω. It operates over a frequency range of 0 to 18 GHz, with a voltage standing wave ratio (VSWR) of ≤1.3 at maximum frequency and insertion loss of ≤0.15 dB. The operating temperature range is -55°C to 125°C, and it is rated for at least 500 mating cycles. Electrical specifications include a dielectric withstanding voltage of ≥1500 V RMS at sea level (50 Hz), insulation resistance of ≥5000 MΩ at 500 V DC, and contact resistance of ≤3 mΩ (center contact, initial).

Materials used include phosphor bronze for contacts, PTFE dielectric, and nickel-plated brass for the body, with a stainless steel body option passivated per ASTM A967. Contact plating is gold over nickel underplate, with a gold thickness of 1.27 μm. The connector is compatible with RG-402 semi-rigid cable.

All values listed are reference ranges for directory purposes and must be verified against the specific model and application with the legal manufacturer or supplier. Standards mentioned are procurement references and do not imply certification or compliance. Users should confirm model-specific parameters, including frequency range, impedance, and environmental ratings, before integration.

Working Principle

The connector uses concentric conductors separated by a dielectric material to maintain a controlled impedance of 50 Ω. The precision mating interfaces ensure consistent electrical contact, minimizing signal loss and reflection. The design supports high-frequency transmission up to 18 GHz, with a VSWR of ≤1.3 and insertion loss of ≤0.15 dB. The dielectric material, typically PTFE, provides stable electrical properties across the operating temperature range of -55°C to 125°C. The connector's mechanical design ensures durability for at least 500 mating cycles, and its materials are selected for reliable performance in communication equipment.
