High-Frequency RF Connector

Product Specifications

Technical details and manufacturing context for High-Frequency RF Connector

Definition

A high-frequency RF connector is a critical electronic component designed to maintain signal integrity while transmitting radio frequency signals between circuit boards, modules, or subsystems. It provides reliable electrical connections with minimal signal loss and reflection across microwave frequency ranges. These connectors are essential in telecommunications equipment, radar systems, test instruments, and wireless infrastructure where precise impedance matching is required. Their robust construction ensures stable performance in demanding industrial environments with vibration, temperature variations, and repeated mating cycles. The connector is engineered with precisely machined conductive interfaces and dielectric materials to achieve controlled impedance, typically 50 ohms, across a frequency range up to 18 GHz. Key performance parameters include a voltage standing wave ratio (VSWR) of ≤1.3 at maximum frequency, insertion loss of ≤0.3 dB, and a dielectric withstanding voltage of ≥1000 V RMS at sea level. The operating temperature range is -55°C to 125°C, and the connector is rated for at least 500 mating cycles. Materials include beryllium copper for contacts, PTFE for insulation, and stainless steel for the body, with gold plating on contacts (50 μin minimum). The connector type is SMA, and typical weight is ≤10 g. These specifications serve as reference ranges; actual values must be confirmed with the manufacturer for specific models and applications. The connector is designed for use in controlled impedance transmission lines, ensuring minimal signal degradation. It is suitable for applications requiring high reliability and repeatability. Always verify model-specific data and compliance with relevant standards before procurement.

Working Principle

The connector uses precisely engineered conductive interfaces and dielectric materials to maintain controlled impedance along the signal path. By matching the characteristic impedance of the transmission line, typically 50 ohms, it minimizes signal reflection and loss at microwave frequencies. The design ensures consistent electrical performance across the specified frequency range, up to 18 GHz, with a VSWR of ≤1.3 and insertion loss of ≤0.3 dB. The materials and construction provide stable operation under temperature extremes and mechanical stress.
